Hi Marc,

For the 30 bit integer issue we had with the parser, I was thinking it would be good to perhaps, instead of doing the test on the AST once its built, try to do the test as number values are being computed in the lexer.

If you're looking for something else to do to help us, we could use a BigInteger type of class, since we currently have no way to represent integers bigger than 30 bits in JavaScript, and even when we do, 64-bit floats can't be used to represent 64 bit integers. If you decide to implement this, you could put it under utility/biginteger.js
