Funny you put your example in the load namespace ;-). Or was that intentional?
I guess we agree to disagree. I find the syntax of
very confusing. And a strange, roundabout way of setting $short.
...without trampling on any potential global namespace...
I think you touch on a very important flaw of my "as.pm" and of Package::Alias' approach as well. Consider a program which has:
Now, Foo.pm has the following shortening (using my syntax for ease of reading):
and Bar.pm has the following shortening:
Then you see we have a problem. One of the two modules will be referring to the wrong long module name, depending on whether an existing stash would be overwritten or not. In other words: you can only have one Shorty. That's because the stash aliasing (or the @ISA assignment) is not limited to the package scope from which it is invoked. And I don't see a way to encapsulate it, as all of the object creation is at run-time.
In my view, this pulls the rug from under any shortening approach currently available. As you cannot create code that can be well-behaved in that respect.
Too bad. It was a nice idea while it lasted... ;-)
