To me, 'hashify' implies taking an assoc array and converting it to hash
form (or perhaps the perl-influenced [a, b, c, d] -> {a=>b, c=>d}). I
still can't think of a name for the useful case :) make_hash, perhaps ..

*(1..10).make_hash {|i| f(i)}

or maybe the complementary hash_to and hash_from, where the block is
respectively the value and the key for the corresponding array entry :)
