However,I had a chance to sprint and they are available now in a new implementation. I did so, rather than improving
plpython,because I believe that native typing and function modules are very useful.

The problem I'm having with this discussion is that every time someone
asks what the supposed advantages of this new Python PL are, a feature
list like the above is dumped, 75% of which is subjective and tends to
use semi-buzzwords, such that then someone else who by his own admission
isn't completely up to date on things says, sure, that sounds great.
Who wouldn't like a "more natural Python environment", "native typing"
and "efficiency", and maybe even "explicitness"?  The current PL/Python
also has, arguably, a more natural Python environment, native typing,
efficiency, and explicitness.  So there you go.  Now what?
