Right, I supposed that that may be the case or at least that you would
feel this way based on your messages from the prior thread.

Does this mean that you are no longer of the opinion that a separate
implementation is acceptable under the circumstances that it provides
major advantages?
Or are you of the opinion that the listed features do not provide
major advantages?
Or, perhaps, more appropriately, that the transitional features do not
provide major advantages?

[transitional features being native typing and reworked function
structure]

That's why I tried to highlight native typing and the reworked
function structure.
Those two features, not to mention Python 3, make it a distinct-enough
beast to justify a different code base, IMO. The rest are icing. Icing
is delicious.

I see Python 3 as a good opportunity to change the interfaces and fix
the design of the PL.

I dunno. I have time to give it some TLC, and I'm not terribly excited
about trying to tack features onto something that I find kinda gross.
