That's a cheap swipe. The regexp doesn't work because I used a colon
instead of a comma, because I acci

A simple improvement would be to also allow the user to pass in a
Random object, in case they have their own source of randomness they
want to use, or for fake Randoms used for wri

One suggestion, though perhaps nothing actually needs changing.
I occasionally run into sites which define their password constraints as
something like "minimum 8 characters, at least one number, one uppercase
letter, and one special character." Their notion of "special" (which in my
mind means an

Looks good! One thing, though:

This is a proposal with a working implementation for a random string generation
template syntax for Python. `strgen` is a module for generating random strings
in Python using a regex-like template language. Example:
>>> from strgen import StringGenerator as SG
