Unfortunately for people optimizing Ruby, corner-case redefinition checks are probably necessary :< Also, I wonder if we can improve rb_funcall to better support inline caching. rb_funcall API is also bad since it cannot use inline cache for method lookup. Maybe a better C API can be introduced for faster function calls from C. Note: I checked commit c5d74afdb4cfea2a4c9ff432d9da82f0649a1e67 by having a "fetch = +refs/pull/*:refs/remotes/ruby/pull/*" line in a "remote" section of my .git/config.
