It's not quite escaping, it's delaying evaluation.  This is the syntax you
would use if you were putting the expression into an alias, so that the
values of the variables would get evaluated when the alias was called, not
when the alias was input.

Yup, or it's the && thing.  && is invalidin python.  Lyntin used to do a
replace on the string of && with and and || with or, but i guess that was
removed at some point in the past.
