Please try again.

There were 3 problems:

- The export syntax didn't have its name set - hence the 'null'.
That was a simple cut-and-paste error.
  
- The export syntax didn't handle compound names (with colons).
The fix was to call the namespaceResolve method.

- Finally, namespaceResolve didn't work if quasiquote is not in
scope, which it isn't by default in a define-library.
