Comment (by nthiery):
For the records, here is where the warning comes from. The BindableClass
things
uses a class BoundClass that inherit from functools.partial. And there
seems to be an issue there:
{{{
sage: import warnings
sage: warnings.simplefilter('error', DeprecationWarning)
sage: import functools
sage: def f(x): return x
sage: g = functools.partial(f,1)
sage: g()
1
sage: class mypartial(functools.partial):
....: def __init__(self, f, i):
....: functools.partial.__init__(self, f,i)
sage: g = mypartial(f,1)
Traceback (most recent call last)
...
----> 3 functools.partial.__init__(self, f,i)
DeprecationWarning: object.__init__() takes no parameters
sage: g()
1
}}}
I had never noticed this. Please explore what's the best workaround!
