Sorry I forgot to reply to the ML too (I have mailmail twice :P)

Hi Jeff,

Sorry I should have searched first. I hate mailman ui...

After reading that thread I totally forgot about
so I think 2.6 is a nice compromise for those of us that want a
simpler syntax. I also find the implementation on the linked thread

How about adding it as a global env variable? that is off by default?
I personally just want to get rid of the % env at the end of almost
every line. and replacing that with .format(env) will actually make
the code almost the same size. In other words I want this
functionality to mimic how the plain shell works with it's variables.
I know it's still magical and first timers could go huh? at it but I'm
sure people will grow to like it as it makes their code a lot cleaner.
