Module.nesting and module_eval

ruby-talk
1

I was wondering why Module.nesting is not consitent when called from
module_eval:

class Object
  def Object.inherited(sub)
    p sub.module_eval { Module.nesting } # [Object]
    p sub.module_eval("Module.nesting") # [A::B, Object]
  end
end

module A
  class B
    p Module.nesting # [A::B, A] OK
  end
  p Module.nesting # [A] OK
end

The evals inside of Object.inherited don't return the same thing. I
think I understand why, classes are objects that can be shared across
bindings but how would I go about fixing this without touching any of
"module A ... end"?

Thanks.

Brian.

Module.nesting uses compile time information if it's available. The
nesting information is not available from within eval and its family
with string, so it tries its best (i.e. [A::B, Object]).
