Ah, so a little more arbitrary than I assumed. I initially hated perl when I first started with it, for what it's worth. I guess you've progressed beyond the point of finding [1] helpful (even if the perl looks a bit strange to me in places). And, apart from Moose I also miss perl's lexically scoped variables :)

It would suck to do numerical work without pandas though. I love pandas.
