Const source location without name
I would like to be able to ask a class or module what its source location is without knowing the name. For example, I want to do this:
module A class B end end p A::B.const_source_location
In other works
A::B.const_source_location would be equivalent to
The reason I want to do this is because sometimes it is very difficult to get the name of a constant, and sometimes I don't have access to the constant that "encloses" the class or module.
ObjectSpace.each_object(Class) do |k| p k.const_source_location end
In this case I have class objects, but I can't tell what constant
k was defined inside of. Also I can't trust the "name" method on
k because sometimes it's not the default method (of course I could work around that, but it's not fun).
I've attached a patch that implements the feature, and there is a PR here
Side note: I think I would like "source_location" better than
const_source_location, but I wanted to just file a feature request so we could talk about the feature in general.
