Given that len(weakset) is defined (sensibly) as the number of currently
active members, it must count. weakset should really have .__bool__
method that uses any() instead of sum(). That might reduce, but not
necessarily eliminate your problem.

I've got a bit of a problem - my project uses weak sets in multiple
areas, the problem case in particular being to indicate what objects
are using a particular texture, if any, so that its priority in OpenGL
can be adjusted to match at the same time as it being (de)referenced

I gather that the .references attribute is sometimes/always a weakset.
To determine its boolean value, it computes its length. For regular
sets, this is sensible as .__len__() returns a pre-computed value.
Indeed. Back
