-------------------------+-------------------------------------------------
Currently, `CachedMethodCaller` inherits the method `precompute` from
`CachedFunction`, but it does not work as expected:
{{{
sage: class Foo(object):
....: @cached_method
....: def f(self, i):
....: return i^2
sage: foo = Foo()
sage: foo.f.precompute(range(2))
f() takes exactly 2 arguments (1 given)
f() takes exactly 2 arguments (1 given)
sage: foo.f.cache
{((0,), ()): 'NO DATA', ((1,), ()): 'NO DATA'}
}}}
It seems that it can be fixed by copying the `precompute` method and
replacing `self.f` by `self._instance_call`.
