Sure, that's what review is about. No?

Okay. I guess I hoped the documentation would help clarify a lot of this, and make the advantages self-evident.

On that:

Ouch. Thanks, that's fixed now. Please take a look again:

Function modules should be pretty obvious. "native typing" is a bit more difficult as a solid understanding of PG's
typesystem is fairly important for a firm grasp.

overwhat you can do with the current pl/python," that would be infinitely more useful than the list of language trivia
relatedto them.  You should be aiming to put Peter on the spot to respond to claims you make like "you can't do this
easilywith the current implementation" after showing an elegant bit of code. 

Okay. So, some examples would help. The documentation is back up, so please be sure to look at the numerous examples
providedtherein. In addition to that, I'll try to get some contrasting examples posted as a follow-up to an earlier
message."In plpython you do X whereas in plpython3 you do Y." 


Thanks.
