It's an intended behavior that Kernel#send ignores refinements as described at https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/RefinementsSpec

What do you think of it, Matz?

Aah, I'm sorry that I missed that part of the documentation.
But indeed I felt the behaviour weird while using the feature in a real-world library.

Updated by matz (Yukihiro Matsumoto) about 8 years ago

Accepted.

The current behavior is according to the direct interpretation of the refinement spec. But many people expect send to be another form of a method call (including refinement). And now I agree with it.
