Keep Hash#symbolize_keys and Hash#stringify_keys ?

[trans]

Consider deprecating Hash#symbolize_keys and Hash#stringify_keys. They seem a bit to magical and #rekey is probably the better approach in any case.

Even if we do deprecate them, we can still keep them as non-core requires.

I think that's not a good idea -- using this outside of Rails is very useful!

Instead they should be fixed!

Okay.

Personally I think you could make them non-core. They are useful.. but they also indicate some poor API usage..

(E.g. JSON and YAML I believe have ways to load strings as symbols, which would be a lot more efficient.)
