I'm not found of pushing everything in the core interpreter, it will become
overwheighted and more difficult to maintain.
A this time I would rather see:
1) adding object support
2) adding error handling support

As those 2 are parts of most used modern language.
Some are afraid of oop but it's really easy to catch.
