Okay, I've tried it and I'll chalk it up to my inexperience with regular 
expressions and sed, but I don't have anyhting to show. The general 
strategy , though, is to make several passes; first escape all inner 
strings, then convert all outer string delimiters (now the only ones not 
escaped) to the immutable symbol. I feel like I'll wake up at 2 a.m. 
with the answer, but I'll post now anyway.
(Assuming you /can/ say "every instance of A between B's" in regex...you 
could always do it with a python script)

Fair enough. Maybe I will submit a PEP for this, I've never looked into 
what's involved.
