I remember this blog post about how optimizing method calls becomes much harder with refinements (from MRI Ruby 2.1):

http://blog.headius.com/2012/11/refining-ruby.html

It looks like JRuby has refinements now but maybe not great support for them (based on just some quick Googling):

https://github.com/jruby/jruby/issues/1062

So I'm curious if anything tested in the article has refinements support.

Personally I'm still skeptical of refinements, but I guess JRuby will have to support them or more and more gems will start to break.
