LDC used to have a --no-runtime switch or something like that, that aborted compilation if a call to the runtime was emitted. I don't know if it still does, but that's extremely useful if you want to use the D subset that only generates assembly without calling to external functions. D runtime is mostly written in D, and for obvious reasons can't use those language constructions that uses the features you are implementing. So is possible (although extremely inconvenient right now). -- Leandro Lucarella (AKA luca) http://llucax.com.ar/ ---------------------------------------------------------------------- GPG Key: 5F5A8D05 (F8CD F9A7 BF00 5431 4145 104C 949E BFB6 5F5A 8D05) ---------------------------------------------------------------------- FINALMENTE EL CABALLITO FABIAN VA A PASAR UNA BUENA NAVIDAD -- Crónica TV
