I never liked the various hacks I had come up with for representing resource handles in Ruamoko. Structs with an int were awkward to test, pointers and ints could be modified, etc etc. The new @handle keyword (@ used to keep handle free for use) works just like struct, union and enum in syntax, but creates an opaque type suitable for a 32-bit handle. The backing type is a function so v6 progs can use it without (all the necessary opcodes exist) and no modifications were needed for type-checking in binary expressions, but only assignment and comparisons are supported, and (of course) nil. Tested using cbuf_t and QFile: seems to work as desired. I had considered 64-bit handles, but really, if more than 4G resource objects are needed, I'm not sure QF can handle the game. However, that limit is per resource manager, not total.
