[Python-ideas] What about allowing '?' in method names?

[Tennessee Leeuwenburg]

Hi all,
Well, the thread's basically concluded, but I'm not sure if it's appropriate
to just 'leave it hanging' seeing as I instigated the thread. So thanks all
for the discussion points and I think we can wrap things up now. Please feel
free to comment on the summary below if you think it doesn't have all the
relevant details.

To summarise the discussion for posterity:

On the Plus Side:
   ? is part of English grammar, and is an intuitive clue-in that a yes/no,
true/false response is expected as a result. Some people (myself included)
would find this an aesthetically pleasing way to label methods which will
come back with a flag.

On the Negative Side:
  ? looks like an operator, not part of the method name, and might confuse
people
  It wasn't mentioned much, but of course there is all the work involved to
change the Python grammar!
  It could collide with external dependencies such as IPython

Outcome:
  It was decided this would not be adopted.

Secondary outcomes:
  A couple of idioms were suggested, such as a trailing capital Q instead
(in my mind, Q for question) of the ?, or _p for predicate. It's possible
people may find it useful to adopt or further discuss such idioms.
