Alternatively, an isVersion(x) predicate that I could use in a static

Well, I've come up with

template isVersion(string ver) {
     mixin(format(q{
         version(%s) {
             enum isVersion = true;
         }
         else {
             enum isVersion = false;
         }
     }, ver));
}

pragma(msg, isVersion!"foo");     // false
pragma(msg, isVersion!"assert");  // true

But it feels hackish too

Not if we put it in the standard library :o). -- Andrei
