Honestly, you guys.  You make things so hard for yourselves.  I don't
see why that wouldn't just be:

    sub infix:!! ($lhs, &rhs) is equiv(&infix:||) {...}

All closures are lazy by definition, and the &rhs forces the right
side of !! to be a closure.  At worst, we'd have to change "sub"
to "macro" to give a special parsing rule to the right side.
