My understanding is that if you have a constructor with no fields, it gets allocated as a compile-time constant. In other words, "C" is just a pointer to a static data structure somewhere in the program binary, and (==) effectively becomes pointer equity.
When used as a general function, at least; my understanding is that it's usually reduced to an integer tag (and that this is relied on to do fast conversions internally)
