- if case_expr is a tuple, the case suite will be executed if switch_expr is a member of the tuple
So there's no way to switch on a tuple?
A tuple can be a member of a bigger tuple:
(1, 'b') in ((1, 'a'), (1, 'b'), (1, 'a', 'b'))
True
Well, yeah, but if you want to match (1, 'b') you'd have to write case ((1, 'b'),). Which is bad for static cases, and even worse for dynamic ones.
