Generics

I dislike the term generics - it's over broad. But I'll put this here until I can resolve some of the conceptual collisions.

Interface Substitution

See Interfaces. This is the primary form of generics.

Values

I want to be able to do something like:

 int<6>

The reason why it's not necessary is that if the call is:

 int.new(6)

then at compile time we'll see that it's static and substitute the response.

The reason why we do need it is that

 var x int<6> = 123456

is a type and it can't be substituted with a different size

 x = int<4>(555) // error

But this collides the concept of interface substitution.

Not Turing Complete

The type system should be static and not Turing complete.

It should also fail quickly in any case that would create an infinite loop (not cause an overflow).
