Blargh.. they do that purposefully to, there's a check if(isCallable!T) on the thingy.

You could use that same check though: if !isCallable!T, it cannot be a property right now, so no need to do the other check.

template isProperty(T) if(isCallable!T) {
enum bool isProperty = (functionAttributes!T & FuncAttribute.property) ? true : false;
}

template isProperty(T) if(!isCallable!T) {
enum bool isProperty = false; // it isn't callable, so can't be a property
}

Error: variable isProperty cannot be read at compile time

...I think I give up. I can't afford to spend any more time on this.

TL;DR, std.traits is extremely brittle, and rather incomplete. As a programmer with deadlines trying to get work done, it is just not yet acceptable >_<
