New submission from Ram Rachum <r...@rachum.com>:
Today I was tripped up by an inconsistency in the `re` docstring. I wanted to
use DOTALL as a flag inside my regex, rather than as an argument to the
`compile` function. Here are two lines from the docstring:
(?aiLmsux) Set the A, I, L, M, S, U, or X flag for the RE (see below).
...
S DOTALL "." matches any character at all, including the newline.
The DOTALL flag appears as an uppercase S in 2 places, and as a lowercase s in
one place. This is confusing, and I initially tried using the uppercase S only
to get an error.
I'm attaching a PR to this ticket.
