As I try not to use indirect object syntax (anymore), I think the approach to define a constant is the most portable way for now. So no argument from me there (anymore).

It is in gross violation of the "do the simplest thing that can possibly work" principle.

I don't agree there. I still think my approach is the cleanest from the user's point of view. It doesn't need the definition of any extra variables or constants, which I think are cruft from an API point of view. And therefore, it is the simplest thing that can possibly work in my eyes.

Under the hood, Perl is already using rather heavy weaponry to DWIM. Constants are one (first create a subroutine, then inline the constant later). Tieing variables is another one. And what about $&? All can be done in other ways, yet everyone likes the fact that they're there if they want to take the performance penalty.

Personally, I think it would not be a real big issue to implement the "as modulename" feature in the C-code that handles "use" in Perl (which would put the namespace aliasing stuff under the hood there). And I think the effect on compiling would be negligeble (only extra complexity while compiling a "use"). However, the reason I'm not going to pursue this, is the global namespace problem. I don't see a simple solution for making the short name local to the package in which it "defined".
