I meant something like...
Class C:
replace = heapreplace
Cs = {}
...
if not isinstance(x, C)
T = type(x)
cls = cache.get(T)
if cls is None:
cls = type('C_'+T.__name__, (C, T), {})
x.__class__ = cls
(Of course, by dynamically reassigning __class__ and using the type
constructor, this checks two of the three "crazy type system voodoo"
boxes. I have no idea if it will work, or if I've made a mistake, or if
you'll be able to understand it in six months.)
