Hmm, your approach is making some sense, I however believe that
Hash#each was chosen
pragmatically and very reasonably so, I guess that Hash#each is the
most used way to iterate over a hash and therefore it is quite
convenient to have a *short* name.
I also believe that #each shall mean "each" and keys being part of the
hash, yielding the keys and the values makes sense too.
