Hi everyone,
Currently, "extern mod" links to external crates and "use" performs
namespace management. It might be preferable to repurpose "use" for both
of these purposes.
So instead of:
extern mod std;
use std::json::Json;
You'd write:
use std::json::Json;
The semantics of this would be that names of external crates form a sort
of "outer namespace" one level higher than the root of the crate being
compiled. Equivalently, it could be understood as "if regular resolution
of a module fails, try to load a crate". This would only work for "use"
statements; explicitly-namespace-qualified identifiers would not be
eligible for this magic.
This is what Python does, and it seems to work quite well for them.
Thoughts?
Patrick
