10:02 PM Ruby Revision cb9c7a6a (git): [ruby/rubygems] Improve error messages and handling in tests

This is a first pass to improve the way errors are handled and raised in
bundler's tests. The goal is to clean up tests and modernize them -
these were some obvious areas that could be cleaned up.
- Instead of raising "ZOMG" in the load... eileencodes (Eileen Uchitelle)

10:47 PM Ruby Revision 6f6a9ead (git): [ruby/rubygems] Replace instance method look up in plugin installer

`Gem::Installer.instance_methods(false).include?(:generate_plugins)` is
63x slower than `Gem::Installer.method_defined?(:generate_plugins)` in a
microbenchmark. The latter is a direct lookup, whereas the former will
create an array, whic... eileencodes (Eileen Uchitelle)

03:31 PM Ruby Bug #21193 (Closed): Inherited callback returns `nil` for `Object.const_source_location`

Since https://github.com/ruby/ruby/pull/12927 the inherited callback no longer can access the `Object.const_source_location`. A simplified reproduction is the following:
```ruby
class A
def self.inherited(other)

07:41 PM Ruby Bug #21168: Prism doesn't require argument parentheses (in some cases) when a block is present but parse.y does

I took a look at this and I'm not sure any of these cases should fail - which would mean the consistently rejected cases are incorrect.
If the argument is wrapped in parenthesis it passes the syntax check (in all cases provided in thi... eileencodes (Eileen Uchitelle)

10:15 PM Ruby Bug #21152: Enumerator's #size returned by Range#reverse_each raises an exception for endless Range

In 3.3 `each` does raise with this example:
```
Range.new(nil,1).each do |x|
p x
end
```
And `reverse_each` does not. It feels like to me that 3.4 is more correct than 3.3. eileencodes (Eileen Uchitelle)

10:12 PM Ruby Bug #21152: Enumerator's #size returned by Range#reverse_each raises an exception for endless Range

This changed in https://github.com/ruby/ruby/pull/12301 to fix a similar bug.
`Range.new(nil, "a").size` also raises a `TypeError` when in 3.3 it didn't. eileencodes (Eileen Uchitelle)

06:19 PM Ruby Bug #21094: Module#set_temporary_name does not affect a name of a nested module

This seems like a bug to me because if you set the temp name before creating `N` it works as you expected. Opened a PR https://github.com/ruby/ruby/pull/12658 eileencodes (Eileen Uchitelle)

07:35 PM Ruby Revision ad96c5a7 (git): [ruby/prism] Throw syntax error for endless method with `[]=`

Prism shoudld throw a syntax error for endless methods when the method
name uses brackets. Previously it would not. This matches the behavior
of parse.y.
