Slang does not currently support the `::` operator for static member lookup, so it must be `Color.Green` and not `Color::Green`. Support for `::` as an alternate syntax could be added later if there is strong user demand. An `enum` type can have a declared "tag type" using syntax like C++ `enum class`: ```hlsl enum MyThings : uint { First = 0, // ... } ``` The `enum` cases will store their values using that type. An `enum` that doesn't declare a tag type will use the type `int` by default. Enum cases are assigned values just like in C/C++: cases can have explicit values, but otherwise default to one more than the previous case, or zero for the first case. All `enum` types will automatically conform to a standard-library `interface` called `__EnumType`, which is used so that basic operators like equality testing can be defined generically for all `enum` types. This change only adds one operator at first (the `==` comparison), but other should be added later. An `enum` case needs to be explicitly converted to an integer where needed (e.g., `int(Color.Red)`). This is implemented by having the main integer types (`int` and `uint`) support built-in initializers that can work for *any* `enum` type (or rather, anything conforming to `__EnumType`). Eventually these will be restricted so that an `enum` type can only be converted to its associated tag type. IR code generation completely eliminates `enum` types and their cases. The `enum` type will be replaced with its tag type, and the cases will be replaced with the tag values. Currently this could leave some mess in the IR where cast operations are applied between values that actually have the same type.
