Thanks for this pointer. I like it this way. So if I now combine your
generator with your suggestion, I end up with something like this:
def extract_names(t, recurse=1):
import string
for _, name, fmt, _ in string.Formatter().parse(t):
if name is not None:
yield name
if recurse and fmt is not None:
for name in extract_names(fmt, recurse-1):
yield name
Pretty cool. Thanks a lot.
