Yes, I have discovered that since I sent my email.

Better than my lisp. It looks good, but I like to keep my virtual envs in the 
folder where the work happens. That is, I create them with =conda env create -y 
-p ./pyenv=. I think this means your code below will fail because it is looking 
for an =/envs/= folder. However, my method allows all virtual environments to 
always have the same name, which could make the code (and testing for the 
existence of that folder) easier.

This can also be handled by =~./condarc= and the default packages installed 
whenever a virtual environment is created.
