I never dealt with Python until the 2.x series, but hasn't Python always been dynamically typed?

Also, the coroutine business seems a significant difference, as Python's concurrency model has always (to my knowledge) been limited by the GIL.

Coroutines != Multithreading. Also as I understand it, GIL places limitations on Python multithreading. Please correct me if I'm wrong.
