[Python-ideas] Fwd: Pattern Matching Syntax

[Andrés Delfino]

I find it weird for case statements to be "inside" match statements.
There's isn't a statement "group" that works this way right now, AFAIK.

This would also be weird:

match X:
case Y:
...

I thought a form based on try would make more coherent:

match:
    suite
case x:
    suite1
else:
    suite2

suite would be executed, and the last expression would be checked against
each case. If no matching case is found, suite2 would be executed.

Does it make sense?
