Python is rather a mess. Code written in Python can't be sped up without pain/cost, and apparently it will never support concurrency natively. It also suffers from the bane of weakly typed languages, errors at run time instead of compile time.

I think the sweet spot for a language with most of Python's benefits that fixes many of its glaring warts is enormous.
