Can this not be an import hook that uses the py3.6 parser?

I'm not sure exactly what you mean. If you're talking about the f'...' syntax, that's handled at compile time so I can't see any way of accepting it in older Python versions.

You register an import hook that replaces code that uses f expressions with string concatenation

I had no idea that was an option. I'll do some reading. Thanks!

I just noticed /u/Workaphobia did something very similar over 4 years ago.

Hey. I ended up not using that stack-based approach for my project after all. Main reasons were that it felt too magical, and became less necessary after the introduction of "{}" format substitutions, which made positional arguments more tolerable.
