I miss 3 things in Perl 5:
- An object system that's built into the language and makes sense. I think C++'s object system is better than Perl 5's. I have to dig through a sea of Class::* modules to write idiomatic OO. This is nonsense, it has got to stop.
- Macros. You can laugh, but you can't hide... Lisp-power macros are very important, IMHO.
- Standard deployment - like PAR. People must undrstand that the real fame for Perl will come when we'll easily install it for the "common people" who don't want to hear about PPMs and compiling modules, god forbid. They want an executable that works.
Luckily, all of the above will be fixed in Perl 6, it seems. So, I'm waiting patiently.
