Nailing my colours to the mast here, I choose '$self'. I will confess
to suggesting the C<use invocant '$whatever'> syntax not because I
thought it was a desperately good idea, but because I didn't want to
get into arguing about what colour to paint the bikeshed before we'd
actually decided whether or not to build the bikeshed in the first
place.
