Indeed that also works for me, and many other deprecation warnings. I should have tried that yesterday. I should explain that I'm working on a deprecation warning for the Matrix.I property. I'm baffled because the warning that I added seems to print sometimes and not other times. Consider for instance, the following code run in the Sage shell, after applying #20904: sage: identity_matrix(ZZ, 2).I <no warning> sage: def a(): sage: return identity_matrix(ZZ, 2).I sage: a() <prints a warning> This is the behaviour in the Sage shell and in Jupyter, while the Sage notebook prints a warning both times! I tried writing a small class with a property and deprecating that, but that works correctly for whatever reason. So I don't know if it could have anything to do with the matrix class being Cython or some other feature of it... Any work-around would be appreciated.
