to_h ()

Recursively unwraps nested ‘Params` objects and constructs an object of the same shape, but using the objects’ internal representations (Ruby hashes) in place of the objects. The result is a hash consisting purely of Ruby primitives.

Mutation warning!

1. This method mutates the internal representation of the `Params`
   objects in order to save object allocations.

2. The value you get back is a reference to the internal hash
   representation, not a copy.

3. Because the `Params` object's internal representation is mutable
   through the `#[]=` method, it is not thread safe. The result of
   getting the hash representation while another thread is adding a
   key to it is non-deterministic.
