Still doesn't give the user a reason for WHY their predicate didn't
compile...

It's a pity we can't do this (or something similar):

template Something(string comp)
{
    static assert( __traits(mixincompiles, comp),
        "Predicate q{"~comp~"} does not compile, because:\n"
        ~__traits(mixinerrors, comp,
                  Something.instantiationFile,
                  Something.instantiationLine) );
}
