Are you aware of every systemwide command that happens to be
implemented in Python, such that you won't execute any of them while
you have the venv active? The ones I mentioned are all installed into
/usr/local/bin or /usr/bin or some other directory on my main $PATH. I
only know they're Python scripts because I just ran "file
/usr/local/bin/*" and had it check them all. If they all reacted to
the activation of a venv, I would have to be extremely careful of
which commands I ever run while a venv is active. Which basically
means I would never activate a venv ever again - not worth it.
