[New-bugs-announce] [issue10516] Add list.clear()

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

Add list.clear() method with obvious semantics.

Pro:
1. parallel to set/dict/defaultdict/deque.clear(),
   usable in generic mutable collection function;
2. makes it easier to switch between list and other collection class;
3. current alternatives are not as obvious;
4. some people seem to expect it.

Anti:
1. unneeded; del l[:] or l[:]=[] do same already.

Guido: (python-ideas list, 'Set Syntax' thread, today)
"FWIW I'm fine with adding list.clear() to 3.3."
