Way back in 2004, when we had the first Java/DynLangs summit, one of the DynLangs guys’ gripes was that bytecodes were too hard to generate. They still are; but check out Charles Nutter’s Bytecode Tools in Ruby: A Low-level DSL; is it just me, or is that remarkable? I have tended to be a bit less impressed than your average Ruby fanboy at a bunch of method calls sans parentheses claiming to be a “DSL”. But man, that looks slick.
