It's an interesting recipe (a beautiful hack, I'd add), but it requires 
implementing the __ror__ method for every command one wishes to support.  If 
we simply pass things to the shell below, that's automatically taken care of 
for us, and it will apply to any command which happens to exist on the system. 
  So I don't see it as something that we should necessarily focus on, at least 
at the beginning.  But for scripting convenience when using python, it would 
not hurt to wrap at least some of the more useful shell commands in 
lightweight proxies which enable this functionality.

I'll certainly keep the idea in the bag for the whole project, so I can remind 
you of it when you are ready to push pysh out the door ;-)

Best,
