I think JIT compilers for Ruby are pretty rare as of now.  Maybe Jruby 
has something that is JIT'y, but I'm not sure.  There is the 'ludicrous' 
optimizer as well as ruby2c, but that's all I know of, and they're 
pretty young.
Yarv uses some inline caching for method signatures but that's about 
where we stand.
Rubinius might be different.
Take care.
