They are different. However, sometimes they are treated as the same(for example, when passed as a method name to `BasicObject#send`).

Hashes with string keys are ubiquitous. Should this idea be accepted, processing them would become a lot simpler.

(Thank you for your corrections of my initial message.)

To the following method

~~~ ruby
def new request:, response:
end
~~~
I'd like to be able to pass both

~~~ ruby
hash_with_symbol_keys = { request: another_hash, response: another_hash2 }
hash_with_string_keys = { 'request' => another_hash, 'response' => another_hash2 }
~~~

I would make a lot cleaner parsing many things returned with string keys(like the output of `YAML.load`).

If you don't like the above feature, could you please at least consider adding `Hash#symbolize_keys`(like you did with `Hash#transform_values`)?
