Just for my understanding: What would happen if someone has functions where some return constant expressions and others not and then that functions are used depending on some other context. E.g: def behaviour2(ctx): return 1 def behaviour1(ctx): return some_calculation_with(ctx) [...] if ... : return behaviour1(ctx) else : return behaviour2() Is that going to raise a warning?
