Hexadecimal support
Thank you for this great package.
It would be nice if 0x for hexadecimal numbers was usable by default. I think the way around it now is to define some sort of hex function within the application.
Pretty sure the core tokenization logic supports it since it goes through scanner.Int. However parseNumber doesn't deal with it -- you could change that to fallback on strconv.ParseInt with a base of 0. (Just saying this based on glancing at the code, didn't do any actual tests.)
Worth noting that gval's base/arithmetic language can't represent actual integers, only float64's. You'll run into precision issues once you go above 1<<53 in magnitude. But of course you could specify a language based on int64's, see e.g. how decimal is handled.
