Actually a nice idea if there were no overhead of creating methods for
all heap instances separately. I'll keep that in mind. :)
What about changing the class of the object to one which is inherited
from its original class and has the method you want? What about reaching
into the class and changing the method in the first place? Either may
not be appropriate, of course, depending on your use case.
There is no base class.
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.)
I think I agree with you that this might be a maintenance nightmare. ;)
Best,
Sven
