Not even good taste <0.5 wink>?  .pth files weren't intended to be a
generally-programmable alternative to site-customize.py, and relying on that
site.py happens to exec entire lines starting with "import" seems abusive to
me.  Stuffing arbitrary executable code on the same line after an import is
a trick, and one I wouldn't count on sticking around.  As Guido said here:


the Python developers have no idea why .pth files exec lines starting with
"import", and that doesn't bode well for the future of this trick.

Guido had a different solution in 1999.  Because it doesn't involve obscure
tricks, envars, or changing anything in the installed Python, nobody liked
it <wink>:


It's not really a solution "for ZODB", though.
