But to do as you suggest, you also need to "mess with environment
variables": PYTHONUSERBASE. Unless you propose changing ~/.local every
time you switch environments, you need to change that variable every
time you switch environments. Therefore your proposed solution must
modify exactly same amount of environment variables as mine.
Your proposal also adds overhead maintaining those collections of .pth
files. For example, if you add a new package to one of your virtualized
environments, you'd need to update every .pth collection directory which
references that environment.
Even ignoring those details I still don't agree. I think adding to a
single environment variable is far cleaner than copying/linking files
around on disks. It can be done easily on a command-by-command basis,
or stowed in a shell script or an alias, not to mention easily managed
by a virtualized environment system like virtualenv.
Shall I put you down as a -1? (I'm not having a lot of luck getting
numeric votes outta folks.)
