Hi, I don't want to keep typing isNumeric!T | isSomeChar!T. I want to type isBuiltIn!T instead, but am trying to work out how to implement it. Something like template isBuiltInT(T) {const bool t=isNumeric!T | isSomeChar!T};} alias isBuiltInT.t isBuiltIn; But that doesn't compile. How should I be doing it? (Of course I'm assuming that isNumeric!T | isSomeChar!T captures all primitives.) Thanks, Luke |

Andrei already answered the main point here, but you are aware | means bitwise OR, right? It might work, but you should use ||. -- Simen |
