Mojo clarifies meaning of "Python superset"

Not so much 'Clarify meaning of "superset of Python"' as 'Remove references to "superset of Python"'

So it won’t be a real superset, and not all valid python programs will be valid mojo programs.

My guess is it will end up pretty close to the C/C++ relationship, where the joke is that C++ is a superset of a subset of C.

Is anyone surprised by this? Chris Lattner in high regard, sure, but I always expected them to have to quietly walk this one back.

It just didn't seem feasible, for a lot of reasons.

Of course, how feasible it sounded will depend on your interpretation of "superset". I wonder what was the straw that broke the camel's back.

Not really surprising that it won't be a strict superset
