To put it in one phrase

In core perl aliasing and other glob-tricks only work with package vars and not lexicals!

Gl*bs are an integral part of the symbol-tabel architecture which aren't available in Lexical Pads! This is one of the breaks of orthogonality in Perl which itch the most and it has been addressed in Perl6.

Now many workarounds have been offered, but for the sake of clarity I recommend sticking with explicit dereferencing.

For me seeing something like  @$a_argument = (1,2,3) somewhere in your code makes it immediately evident that the callers argument is altered, without needing to check how the arguments where passed in the head of the routine. (Otherwise I would recommend to suffix the name of the variable with something like "_alias").

I can hardly imagine occasions where you need to do this more than once, and if you encounter one of these situations, better try one of the other recommended workarounds like our + local or Data::Alias .

Cheers Rolf
