That's 7 characters more you'll need to write all the time! Also you'll need to remember to prepend them to all scrips, ie pip, fab etc. Well that seems to me to be more error prone for juniors than telling them to always use a virtual env (ie have (envnane) in their prompt)!!

It's less error prone. Never had ^^ that scenario since and I've not run into additional problems either.

Having an extra 7 characters in a ./run.sh script doesn't really bother me. I'm not a perl developer.
