Make SomeIPythonRepr traverse the MRO for the type? #36801
Description
Problem Description
Currently the implementation of SomeIPythonRepr just check the type of the function:
sage/src/sage/repl/display/fancy_repr.py
Lines 150 to 155 in b281350
Would it be desirable to traverse the MRO instead?
What's the difference? This affects the printing when there's some user class inherit from one of the default IPython-printable classes.
sage: class A(list):
....: pass
sage: A([1..30])
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]
sage: [1..30]
