The 'code' you read is similar, but the way they work are totally different.

Monkey is fundamentally a functional language, but rooby is totally an object oriented language. And the compiler, vm's internal implementation and bytecode spec, which are the 'core' of rooby, is not like monkey at all.

I would say I extended monkey's lexer and parser as rooby's. I feel sorry if I didn't give enough credit to Thorston, I would add reference to his book in readme. But the core is more a Ruby than monkey, so I don't think it's just an "extension" of monkey.

Please read the commits and you'll know how much work I did to make rooby, it's far more complicated than just "extend" monkey.
