That always chafed me about Scheme. I see the utility of `eq?` and `eqv?`, but I'd prefer that there were only `equal?` and functions were defined to get an object's "id" or "numeric equivalency class," or whatever, instead of having different flavors of data structures that differ only for certain values.
