The main thing is that you can introduce new keywords, something which is not easy to do otherwise. If Perl 5.8 had had that feature already, you could have implemented the given keyword as a Perl module.

Of course, having a mutable language is nothing new - Lisp had it 40 (or is it 50) years ago with its macros.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
