in reply to What would you change?
Actually, I think the changes I'd most like to see revolve around making perl a bit friendlier towards functional and OO programming. Function/method definition and invocation could be less verbose. See for example Method::Signatures for a step in the right direction (Moose is lovely too, of course).
update: Oh, I forgot! I would absolutely love to have lvalue methods that work. I'm getting really tired of having to write $foo->bar( $foo->bar() + $wibble ). I'd like to be able to use more syntax than just ->() once in a while.
