So, consider a set of overloads: void f(T)(T t) if(isSomething!T) {} void f(T)(T t) if(isSomethingElse!T) {} void f(T)(T t) {}
I have a recurring problem where I need a fallback function like the bottom one, which should be used in lieu of a more precise match. This is obviously an ambiguous call, but this is a pattern that comes up an awful lot. How to do it in D? I've asked this before, and people say: void f(T)(T t) if(!isSomething!T && !isSomethingElse!T) {} Consider that more overloads are being introduced by users spread out across many modules that define their own kind of T; this solution is no good.
