It wouldn't hurt to take a morning and just skim them. It is hard for me 
to know what you will consider important enough to want in Prothon 1.0 
or even Prothon 5.0. Here are some random interesting ones:

It is hard to know what of Python is in Prothon and what is missing. You 
don't know Python well enough and I don't know Prothon well enough.
