Issue 7362: Incorrect error message with def((x)=0) (original) (raw)

def f((x)=0): pass

gives the following incorrect error message:

SyntaxError: non-default argument follows default argument

"def f((x)): pass" is treated exactly the same as "def f(x): pass", so it would seem sensible for the same to be true if a default value is used. But if this syntax is disallowed for some reason, the error message should be fixed.

This appears to be related to bug #1557232.
