The part about "no runtime costs" is not correct.  Requiring a "proper" 
equals method imposes the requirement that the captured args be able to 
be reconstituted on demand, which likely has additional costs for 
capture and/or footprint.

I'm not saying this is not desirable, I'm just saying don't kid yourself 
that its free.
