☆ on the current Parrot is hopelessly slow. The startup time reminds me of what it used to be like to run a Python program without the precompiled bytecode. The good news is that Parrot is being unfucked. I guess when you take a decade to get to this point, rewriting the VM and imcc isn't something you flinch at.
They've brought in a lot of things that just didn't fit in Perl 5. The type system in particular is finally sensible allowing you to constrain the DWIM semantics in a natural way, in fact a lot of changes seem to make it natural to subvert unintended DWIMmery. You can actually mean "do what I say." My biggest issue with Perl so far has been general abuse of numbers. I might start writing Perl again.
