@robryk Cool stuff, but kinda seems to miss the point of most people using (to a lesser extent ba)sh -- it's everywhere. If you assume you can install arbitrary software then Python is already kinda an acceptable scripting solution, innit?
@timorl If you want to do standard shell things (like pipes), then Python is cumbersome (and lets you rediscover funny edge cases that are normally handled by the shell -- I'm not aware of a Python library that helps with that).
@robryk Hm, fair. Still, it's a very (surprizingly) niche usecase I feel.
