In Ruby 2.3 or later, `String#+@` is available and `+@` is faster than `dup`.
```ruby
# frozen_string_literal: true
require "bundler/inline"
gemfile(true) do
source "https://rubygems.org"
gem "benchmark-ips"
end
Benchmark.ips do |x|
x.report('+@') { +"" }
x.report('dup') { "".dup }
x.compare!
end
```
```
$ ruby -v benchmark.rb

### Summary
This PR changes .rubocop.yml.
Regarding the code using `if ... else ... end`, I think the coding style
that Rails expects is as follows.
```ruby
var = if cond
a
else
b
end
```
However, the current .rubocop.yml setting does not offense for the
following code.
```ruby
var = if cond
a
else
b
end
```
I think that the above code expects offense to be warned.
Moreover, the layout by autocorrect is unnatural.
```ruby
var = if cond
a
else
b
end
```
This PR adds a setting to .rubocop.yml to make an offense warning and
autocorrect as expected by the coding style.
And this change also fixes `case ... when ... end` together.
Also this PR itself is an example that arranges the layout using
`rubocop -a`.
### Other Information
Autocorrect of `Lint/EndAlignment` cop is `false` by default.
https://github.com/bbatsov/rubocop/blob/v0.51.0/config/default.yml#L1443
This PR changes this value to `true`.
Also this PR has changed it together as it is necessary to enable
`Layout/ElseAlignment` cop to make this behavior.

A few have been left for aesthetic reasons, but have made a pass
and removed most of them.
Note that if the method `foo` returns an array, `foo << 1`
is a regular push, nothing to do with assignments, so
no self required.

|

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

- Using `references` or `belongs_to` in migrations will always add index
for the referenced column by default, without adding `index:true` option
to generated migration file.
- Users can opt out of this by passing `index: false`.
- Legacy migrations won't be affected by this change. They will continue
to run as they were before.
- Fixes #18146

Syntax was chosen to follow the passing of multiple options to
decimal/numeric types. Curly braces, and allowing any of `,`, `.`, or
`-` to be used as a separator to avoid the need for shell quoting. (I'm
intending to expand this to all columns, but that's another PR.
The `required` option will cause 2 things to change. `required: true`
will be added to the association. `null: false` will be added to the
column in the migration.

ActiveRecord::Base.pluralize_table_names = false.
Previously, generation a migration like this:
rails g migration add_column_name_to_user name
would not generating the correct table name.
Fixes #13426.

For instance, running
rails g migration CreateMediaJoinTable artists musics:uniq
will create a migration with
create_join_table :artists, :musics do |t|
# t.index [:artist_id, :music_id]
t.index [:music_id, :artist_id], unique: true
end

For instance,
$ rails g model Product supplier:references{polymorphic}
generate model with `belongs_to :supplier, polymorphic: true` association and appropriate migration.
Also fix model_generator_test.rb#L196 and #L201

* Move reference? method to class to remove duplicated code
* Move to_sym typecast from #initialize to .parse method (make it
easier to refactor reference?), remove AS object/blank require
* Use []= instead of merge!({})
* Remove in? in favor of include?, remove AS object/inclusion require

options into constants and while doing so, there was a minor error of
using a wrong constant name.

After a long list of discussion about the performance problem from using varargs and the reason that we can't find a great pair for it, it would be best to remove support for it for now.
It will come back if we can find a good pair for it. For now, Bon Voyage, `#among?`.

There're a lot of places in Rails source code which make a lot of sense to switching to Object#in? or Object#either? instead of using [].include?.
