So? It's been evaluated successfully. What more is there to do?

Expose that tooling via the standard library. It's just pure functions.

What consequences? Isn't CPython forced to do all the nasty stuff anyhow when it's a language feature?

Frame hacks with sys._getframe necessarily imply dynamic scope not lexical scope. Dynamic scope does not work with nested functions, including comprehensions. See this issue with the htm library, https://github.com/jviide/htm.py/issues/11
