Return values for open() and define_c_*()

I have a suggestion, how if open() returns the C file handle (on windows and linux), define_c_*() and routine_id() returns the memory address (as it is now with call_back()). But still return -1 when there is a failure. Why? - Won't break existing code (we usually write fn = open(...) if fn = -1 then error -- or if fn < 0 then error something = define_c_func(...) if something = -1 then error don't we?) - Easier interface with windows API that requires a file handle or callback function (we dont have to open() the file using Windows API) - Faster execution (eu interpreter don't have to translate the routineid/filenumber into an internal representation) - call_back() can be replaced easily with: function call_back(object x) return x end function
