This does NOT mean Python will get Tail Call Optimization, as Guido cannot be shown The Light, and has decided.
That's probably one of the more frustrating things about Python. Each release it gets all sorts of questionable new syntax (including the very strange pattern matching "feature" that kind of sucks compared to something like Erlang or Scala), but we never get real useful quality of life improvements for basic functional programming like TCO or multi line lambdas
The utility value of multi-line lambdas is real, but the readability of these is terrible. And Python prizes readability. So you know where this initiative will end up.
Nothing more readable than a triply-nested list comprehension on an object that exists only to vend its __getattr__ for some unholy DSL
