weakrefable 0.0.1

No project description provided

If you use the weakref module, you may be aware that some object do not support being weakly referenced to. For example, built-ins dict and list.

Trying to create a weak reference will raise a TypeError.

There does not seam to be any way from Python itself to check whether an object can be weakref’d, though the CPython C-layer make that pretty easy.

This just exposes this functionality at the python level
