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

The should make it easier for apps to rescue ActiveModel specific
errors without the need to wrap all method calls with a generic
rescue RangeError.

Since precision is always larger than scale, it can actually change
rounding behavior. Given a precision of 5 and a scale of 3, when you
apply the precision of 5 to `1.25047`, the result is `1.2505`, which
when the scale is applied would be `1.251` instead of the expected
`1.250`.
This issue appears to only occur with floats, as scale doesn't apply to
other numeric types, and the bigdecimal constructor actually ignores
precision entirely when working with strings. There's no way we could
handle this for the "unknown object which responds to `to_d`" case, as
we can't assume an interface for applying the scale.
Fixes #24235

This type adds an escape hatch to apps for which string duping causes
unacceptable memory growth. The reason we are duping them is in order to
detect mutation, which was a feature added to 4.2 in #15674. The string
type was modified to support this behavior in #15788.
Memory growth is really only a concern for string types, as it's the
only mutable type where the act of coersion does not create a new object
regardless (as we're usually returning an object of a different class).
I do feel strongly that if we are going to support detecting mutation,
we should do it universally for any type which is mutable. While it is
less common and ideomatic to mutate strings than arrays or hashes, there
shouldn't be rules or gotchas to understanding our behavior.
However, I also appreciate that for apps which are using a lot of string
columns, this would increase the number of allocations by a large
factor. To ensure that we keep our contract, if you'd like to opt out of
mutation detection on strings, you'll also be option out of mutation of
those strings.
I'm not completely married to the thought that strings coming out of
this actually need to be frozen -- and I think the name is correct
either way, as the purpose of this is to provide a string type which
does not detect mutation.
In the new implementation, I'm only overriding `cast_value`. I did not
port over the duping in `serialize`. I cannot think of a reason we'd
need to dup the string there, and the tests pass without it.
Unfortunately that line was introduced at a time where I was not nearly
as good about writing my commit messages, so I have no context as to
why I added it. Thanks past Sean. You are a jerk.

Any tests for a type which is not overridden by Active Record, and does
not test the specifics of the attributes API interacting in more complex
ways have no reason to be in the Active Record suite. Doing this
revealed that the implementation of the date and time types in AM was
actually completely broken, and incapable of returning any value other
than `nil`.

Things like decorations, overrides, and priorities only matter for
Active Record, so the Active Model registry can be implemented much more
simply. At this point, I wonder if having Active Record's registry
inherit from Active Model's is even worth the trouble?
The Active Model class was also missing test cases, which have been
backfilled.
This removes the error when two types are registered with the same name,
but given that Active Model is meant to be significantly more generic, I
do not think this is an issue for now. If we want, we can raise an error
at the point that someone tries to register it.
