8.0 Tuple parentheses optional in switch expression and statement #576
Description
When a tuple is used as the expression for a switch statement (or expression), the tuple doesn't need parentheses. For example:
void M(bool a, bool b)
{
switch (a,b) // This is the tuple (a,b), but the parentheses are for the switch expression, not the tuple.
{
case (true, true):
break;
case (true, false):
break;
case (false, true):
break;
case (false, false):
break;
}
}
