Re: Learning to *really* love references

Perl really needs better aliasing features. Currently, you can only create an alias with a package variable (using a glob) or in a for-loop. Other methods require you to use tie() or some other less elegant means.

While afaik you cant alias scalar directly you can do aliasing with arrays and hashes using Array::RefElem and even do aliasing with arrays without anything more than the following utility sub: `sub alias_array { \@_ }` [download] But you are right, perl needs better ways to define and manipulate aliases.

Monks~ Well, it might not do much now, but Perl6 will support aliasing via the := operator... That doesn't help you in the short run, but after reading the apocalypses (especially 4) I have been waiting with bated breath for Perl6.
