Actually I find sub (passing a function as "repl") more useful than
findall (finditer is roughly as useful as sub), but sub's documented
on the same URL, anyway. Not everybody likes working "by callbacks",
which is what sub + a function lets you do -- findall and finditer
are more direct, and finditer is basically just as powerful as sub,
as it returns match-objects one after the other, while findall just
returns a list of substrings, not quite as powerful -- though surely,
some of the time (when that's all you need), it may be even handier.
