Because it's probably coming from a constraint, you probably can't 
figure out the exact usage. What's more annoying is that likely it is a 
spurious warning. A lot of traits "try something", and then alias to 
false or true depending on what works. But it's not going to make a 
difference in your code.

It's one of the most annoying things in the library. If you see this 
warning coming from *your* code, then you should fix it. But it will 
tell you the location if that was the case, not std.traits.
