Comment:
It looks good about the `_call_` problem but there is some others...
{{{
sage: PF4 = ParkingFunctions(4)
sage: sage: a = PF4.list()[36]
sage: sage: b = PF4([1,3,2,1])
sage: a.parent()
Traceback (most recent call last):
...
AttributeError: 'ParkingFunction_class' object has no attribute 'parent'
sage: a
[1, 4, 2, 1]
sage: b.parent()
Traceback (most recent call last):
...
AttributeError: 'ParkingFunction_class' object has no attribute 'parent'
}}}
It seems (to me) to be easily "rewritable" with that ticket #16465. (It
could be a test of that design...).
