Functions are definitely not subshells in Bash, seeing as anything modifying the environment, like pyenv and such, is implemented as functions instead of scripts — specifically because functions are run in the same shell instance.

Unless 'subshell' means something in the vein of 'like a new shell, but not really'.

You're right, my bad, I got this mixed up with something else.

Try doing cd inside a function and then pwd in the main script. Does it move the main script too?

I'm gonna bet yes for the simple reason that various helper scripts exist that do advanced cd history, with fuzzy search and whatnot, and they can't be implemented as anything other than functions.
