In the above code you can:
* use the walrus operator := to simplify the code by doing the assignment in the
if statement;
* use the fact that group can accept a tuple instead of a single argument.
```
if m := regexp.match(document.body[k]):
pretext, cmd, arg, posttext = m.group(1, 2, 3, 4)
```
I like this version because it is shorter and IMHO it is easier to read. On the
other hand this is a matter of taste and the above code is correct.

Best regards,
PS: I need to use a real emoticon or else Scott's script will consider the
walrus as emoticon, thus this reference makes the false positive a true positive
:-D
