content_tag's first argument is will generate a string with an html tag so `:a` will generate: `<a></a>`. When this happens, the symbol is implicitly `to_s`-d so a new string is allocated. We can get around that by using a frozen string instead which

No idea why on earth this hash key isn't already optimized by MRI, but it isn't. :shit:

When an unknonwn key is passed to the hash in `PRE_CONTENT_STRINGS` it returns nil, when you call "#{nil}" it allocates a new empty string. We can get around this allocation by using a default value `Hash.new { "".freeze }`. We can avoid the `to_sym` call by pre-populating the hash with a symbol key in addition to a string key.
We can freeze some strings when using Array#* to reduce allocations.
Array#join can take frozen strings.
This change buys us 86,600 bytes of memory and 1,857 fewer objects per request.

I wrote a utility that helps find areas where you could optimize your program using a frozen string instead of a string literal, it's called [let_it_go](https://github.com/schneems/let_it_go). After going through the output and adding `.freeze` I was able to eliminate the creation of 1,114 string objects on EVERY request to [codetriage](codetriage.com). How does this impact execution?
To look at memory:
```ruby
require 'get_process_mem'
mem = GetProcessMem.new
GC.start
GC.disable
1_114.times { " " }
before = mem.mb
after = mem.mb
GC.enable
puts "Diff: #{after - before} mb"
```
Creating 1,114 string objects results in `Diff: 0.03125 mb` of RAM allocated on every request. Or 1mb every 32 requests.
To look at raw speed:
```ruby
require 'benchmark/ips'
number_of_objects_reduced = 1_114
Benchmark.ips do |x|
x.report("freeze") { number_of_objects_reduced.times { " ".freeze } }
x.report("no-freeze") { number_of_objects_reduced.times { " " } }
end
```
We get the results
```
Calculating -------------------------------------
freeze 1.428k i/100ms
no-freeze 609.000 i/100ms
-------------------------------------------------
freeze 14.363k (± 8.5%) i/s - 71.400k
no-freeze 6.084k (± 8.1%) i/s - 30.450k
```
Now we can do some maths:
```ruby
ips = 6_226k # iterations / 1 second
call_time_before = 1.0 / ips # seconds per iteration
ips = 15_254 # iterations / 1 second
call_time_after = 1.0 / ips # seconds per iteration
diff = call_time_before - call_time_after
number_of_objects_reduced * diff * 100
# => 0.4530373333993266 miliseconds saved per request
```
So we're shaving off 1 second of execution time for every 220 requests.
Is this going to be an insane speed boost to any Rails app: nope. Should we merge it: yep.
p.s. If you know of a method call that doesn't modify a string input such as [String#gsub](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37) please [give me a pull request to the appropriate file](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37), or open an issue in LetItGo so we can track and freeze more strings.
Keep those strings Frozen

This will silence deprecation warnings.
Most of the test can be changed from `render :text` to render `:plain`
or `render :body` right away. However, there are some tests that needed
to be fixed by hand as they actually assert the default Content-Type
returned from `render :body`.

This is already supported in `ActiveSupport::Inflector#pluralize` and `String#pluralize`, so we just forward the locale.

If a template includes `# Template Collection: ...` anywhere in its
source, that name will be used as the cache name for the partial that is
rendered for the collection.
This allows users to enable collection caching even if the template
doesn't start with `<% cache ... do %>`.
Moreover, the `# Template Collection: ...` notation is recognized in all
template types (and template types other than ERB can define a
resource_cache_call_pattern method to allow the `cache ... do` pattern
to be recognized too).

Adds the `virtual_path` option to `cache_fragment_name` so it can
be provided when needed.
That allows `cache_collection_render` to get the appropriate cache
key with the digest generated based on the template and prevent
collision with other templates that cache the same collection.

Previously, passing a falsey value to `include_blank` would be ignored if the
field was required, and a blank line would still be inserted. The following will
now raise instead of quietly failing:
`select("post", "category", %w(a required field), { include_blank: false }, required: 'required')`

stevenspiel/link_to_if_block_helper_addition"
This reverts commit d459b001b43d25053e7982e96eb8383538a6e358, reversing
changes made to 4d4950fae9e2a6970b5f1793aadc56a0b44e28a3.
:sweat:
The block is not supposed to be passed to `link_to`. It's used for a
customized behavior of the `condtion = false` case. The docs
illustrate that like so:
```
<%=
link_to_if(@current_user.nil?, "Login", { controller: "sessions", action: "new" }) do
link_to(@current_user.login, { controller: "accounts", action: "show", id: @current_user })
end
%>
```

The documentation previously stated that calling `translate(".foo")` was
equivalent to calling `I18n.translate("people.index.foo")` which is
incorrect due to the various other functions of the `translate` view
helper. This has been fixed.
Additionally, a note about forcing the view helper to re-raise
exceptions was added to the section detailing the handling of missing
translations.
Other cleanup includes:
* Consistent formatting of code
* Stop indenting bulleted list as a code sample
* Tighten some of the language
* Wrap at 80 characters.
