I think the problem is in the API. That's what makes it too complex.
There are too many cases of specific handling and options (see below):

1. Unnecessary option: if the key is supposed to stay intact the block
should just return the original key.

2. Why that default? In my mind this is too much implicit logic.
Also this can be easily achieved with
hash.rekey(&:to_sym)

3. I would change that to EITHER block OR map argument, but not both.

If one needs a special key one can use a Symbol for that as
efficiently as nil. nil is the value return if something is absent
and I believe it does not make for a good key in a Hash.

class Hash
def rekey(mapping = nil, &convert)
c = convert || mapping
dup.tap do |h| # preserve type and defaults
h.clear
each_pair {|k, v| h[c[k] || k] = v}
end
end
end
