[New-bugs-announce] [issue10360] _weakrefset.WeakSet.__contains__ should not propagate TypeErrors

Tres Seaver report at bugs.python.org
Mon Nov 8 15:12:43 CET 2010

New submission from Tres Seaver <tseaver at agendaless.com>:

Because application code which tests for the presence of
an object in a WeakSet may not be able to ensure that the
object is weak-referenceable, the set should just return
False for any object passed to '__contains__' which causes
'ref' to raise a TypeError.

Patch forthcoming.
