Mojo clarifies meaning of "Python superset" (github.com)

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

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

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

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.
