Feature #20428: Ability to reference current class/module in lexical scope
https://bugs.ruby-lang.org/issues/20428
* 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
```

Issue #20428 has been updated by ufuk (Ufuk Kayserilioglu).
I think you should be able to use `Module.nesting.first` to get the closest lexical nesting to the executing code. There might be edge-cases where this doesn't work the way you might want it to work, but it definitely works for your example:
```ruby
module Foo
module Bar
def blah
puts "executing from #{Module.nesting.first}"
end
end
end
class Baz
include Foo::Bar
def blah
super
puts "executing from #{self.class.name}"
end
end
Baz.new.blah
```
outputs
```
executing from Foo::Bar
executing from Baz
```
