           Summary: Allow switch with multiple arguments
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd

Allow `switch` statements to have more than one argument: `switch (x, y)`.
Case labels then take the same number of arguments: `case (0, 0):`
The parentheses after `case` are then required.

A case label matches if it would match components individually.

While this should work for all types for which `switch` works, if the type of the components’ sizes adds up to ≤ 64 bit, arguments can be connected into an `ulong` (or smaller) and checked together.
