I think this is a better example

I _think_ that maybe if you have a tuple of 1, it gets "unwrapped" in
some way to be just a singleton - or at least I was encountering a
bug along those lines...

(('/mnt/tmp', 'mount /mnt/tmp'))[0] == '/'
^ this is where my big was occuring, I think

It also could've been an issue with the printing - no idea.
Changing from a tuple to a list seems to be better
