Reference to module root

[jwerle]

It would be pretty convenient to support an identifier or keyword that references the root of the module much like certain usage of Rust's crate keyword.

@aep what are your thoughts?

Yes!

Actually an absolute path might work already.

using ::string;

[jwerle]

hmm, it doesn't seem to work if I want to do something like:

// a.zz

export fn foo() -> int {
  return 123;
}

// b.zz

export fn bar() -> int {
  return ::a::foo();
}

// lib.zz
export using a::{ foo }
export using b::{ bar }

[aep]

oh in b.zz you can just do "using a"

and the lib can be accessed by its module name.
