Jamaica from Judoscript is a bit similar but with more java-like syntax: http://www.judoscript.org/articles/jamaica.html.
It's build on top of ASM or BCEL, but I guess it's outdated as the last release is from 2005. However, JVMScript looks much better. It's Ruby after all. :) Thanks Charlie, I'll try it.
