So you mean runtime efficiency.

I once cooked something together.  The code is on Ruby Garden:
http://wiki.rubygarden.org/Ruby/page/show/MethodHooks

No idea about performance etc.  At some point I stopped working on this 
because it was said that Ruby 2 will include a feature for this.  I 
remember that there were some limitations (i.e. no suppport for blocks 
so far) but usability is ok IMHO.  This was mostly an experiment.

Kind regards
