Allowing dissoc and select-keys to accept both keys as arguments and
as a collection would be nice, and backwards compatible. In any case,
ostensibly it should be consistent; otherwise, it's just an
idiosyncrasy in the language that people will have to deal with. I
wonder what the reasoning is behind it, or if it was completely
arbitrary.
