I agree for common classes this could be a problem, but I don't think
it would be any less of a problem than the existing support for
wildcards. I see this more as a solution targeted mostly for long
package names with overlapping class names. I'm going to need to
think some about what "readable" really means, and would be interested
in any thoughts on this topic.

Thanks for pointing this out, it's definitely a huge hole in the proposal.

Thanks for the pointer. I, too, would probably vote against a the proposal of
import Map<String,Integer> as CodeValueMap;
Several of the related bugs mention this syntax, but I think this
combines two issues together. It seems to me that the simple mapping
of a fully-qualified class name to a "short" name is separate from the
typedefing of a specifically-parameterized generified type to a short
