02/21/2023, 1:45 AMGiven a PEX, what's the incantation to know what the latest compatible Python version would be? E.g. Given
foo.pex3.8bitter-ability-32190

So, what I'm thinking is instead of trying to get "ahead" of PEX with choosing the right interpreter, it'd be easier to just "go-with-the-pex-flow" and just ask it what it needs
