There's something vaguely resembling an implementation of this in Python
at http://home.uchicago.edu/~wolfson/Python/scanstr.py [+.html]

Also, I discovered that the nested scopes (with and without a
from-__future__ import) dumped core when dealing with the following list
comp:

[[locals.append(here),remotes.append(there) for here,there in\
  [stripped.split('\t') for strippied in\
   [line.strip() for line in open(fn).readlines()]\
   if stripped]\
  if path.exists(here)] for fn in filenames if path.exists(fn)]
