It absolutely does--apologies for using up your time informing me of an existing API! Thank you!

Feature #20428: Ability to reference current class/module in lexical scope
https://bugs.ruby-lang.org/issues/20428#change-107908
* Author: harrisonb (Hazel Bachrach)
* Status: Open
----------------------------------------
Hello! As far as I know, there is no way to reference the current `Class` or `Module` one is inside of lexically in Ruby. Would it make sense to add a syntax/keyword for this?
``` ruby
module Foo
module Bar
def blah
puts "executing from #{magic_new_keyword}"
end
end
end
class Baz
include Foo::Bar
def blah
super
puts "executing from #{self.class.name}"
end
end
Baz.new.blah
```
What I'm hoping for is
```
executing from Foo::Bar
executing from Baz
```
