// First we text a variadic macro with the default variadic
// parameter name (`__VA_ARGS__`) and other non-variadic parameter.

// Next we test a varadic macro where the variadic parameter
// has been given an explicit name.

// Finally, we test the case where the variadic parameter
// might have zero arguments passed for it, so that
// the result produces a trailing comma.
//
// TODO: If we add support for deleting trailing commas
// in these cases to Slang, we can update this case to
// test that support.
