Ah didn't know that. That's a solution for ebuilds anyway. How about for eclasses and user bashrc files? Does whatever EAPI setting is in effect for a particular ebuild apply to them? It isn't really worth toggling it on and off for individual files or functions in order to not break certain eclasses that conflict.

That point was reached when someone decided a custom Bash parser just for ebuilds was necessary.
