Test: ``` scss // Test 1 @mixin test($a, $b) { content: $a $b; } test { @include test(("a": 1, "b": 2)...); } ``` ``` scss // Test 2 @function test($a, $b) { @return $a $b; } test { content: test(("a": 1, "b": 2)...); } ``` Expected result for both tests: ``` css test { content: 1 2; } ``` Results: ``` css stdin:8: mixin test has no parameter named $"a" ``` ``` css stdin:8: function test has no parameter named $"a" ```
