In the past, I have suggested using the "default" keyword to specify a
fallback function of this kind. I think it's a useful pattern for generic
algorithms that have optimized variants on specific types for
performance.
void f(T)(T t) if(isSomething!T) {}
void f(T)(T t) if(isSomethingElse!T) {}
void f(T)(T t) default {}
It's an interesting idea... flesh out a DIP?
We're better off without that. -- Andrei
Then we need a decent way to do this.
Use static if inside the function. The entire notion of "call this
function if you can't find something somewhere that works" is
questionable. -- Andrei
