Yeah, I uploaded a new version that has use 5.008 because I use the new prototype \[$@%], which means "expect a scalar, array, or hash, and auto-ref it".

As far as back-porting it, I would suggest a prototype of $$, and require the user explicitly reference the variables. The other solution is three functions, one for scalars, one for arrays, and a third for hashes; I suppose that's ok too. So let's do both:

package Lexical::Alias; # alias() is the XS function # with a prototype of ($$) # the following are merely wrappers sub alias_s (\$\$) { goto &alias } sub alias_a (\@\@) { goto &alias } sub alias_h (\%\%) { goto &alias } 1;
Well, that was awfully easy. But here's the deal. I'll make two functions in the XS file -- one for pre-5.8, and one for post-5.8. When the module is used, it'll alias (how funny!) alias() to the proper one.
