Thanks, downs, worked great. You forgot a pair of parens, so for others'
reference here's the current implementation of binaryPred in std.functional:

template binaryPred(string comp) {
    // @@@BUG@@@: typeof(mixin(comp)) should work
    typeof({ ElementType a, b; return mixin(comp);}())
    binaryPred(ElementType)(ElementType a, ElementType b)
    {
        return mixin(comp);
    }
}

unittest
{
    alias binaryPred!(q{a < b}) less;
    assert(less(1, 2) && !less(2, 1));
    assert(less("1", "2") && !less("2", "1"));
}
