Nexoniarz 04eb0cce55 generics (in the compiler written in Finch)
fn max[T](T a, T b) -> T      struct Stack[T] { []T items }      fn Stack[T].push(T x)

The type is worked out from the arguments (max(3, 4), first([1, 2])) and written out
where it cannot be: max[float](1, 2.5), Stack[int](), Pair[str, int](...). Each use makes
its own copy, so a generic costs nothing at run time. Several parameters
(Pair[A, B]), nesting (Stack[Pair[int, str]]), methods, and printing (Stack[int](items: ...))
work. An error inside a generic says which version it was building.

boot.sh: 37 passed, 0 failed (stage 2 and 3 identical).
