41b7d6d74d One last refactoring of the import handling: 
* Create an import resolving stage. Currently this involves a copy of the ast,
  we can probably revisit this once we revisit doing full copies of the ast in
  general.

* Don't repeat work. Once we resolve a import, put it on a hash table and use
  it next time we are asked for it. This solves a O(n^2) behaviour in
  degenerated cases.

* Once import resolution is done, the target of an import is stored on the
  import itself.

a8eeec1dbd Sketch support for reading multi-file crates in rustc. Add test, not yet working. 2011-01-10 18:18:16 -08:00
Rafael Ávila de Espíndola
2fb09eb585 Add sufficient import support to compile some simple single-crate programs. 
This is likely not the final solution. It does repetitive work and doesn't produce
errors for invalid but unused imports. In any case, I think it is a useful step.
 2011-01-07 15:17:18 -08:00

"unimplemented definition variant for: foo" in

use foo;
fn main(vec[str] args) {
   foo.bar();
}
