So I noticed that hash with indifferent access is not indifferent to
integers as keys.
Currently this doesn't work.
hash = HashWithIndifferentAccess.new({"1" =>3})
hash[1] # => 3
The specific use case for me was passing around ids from the browser which
was necessary because the form was using dynamic fields generated from
database records, like a form with questions stored in the database.
We could make hashes with indifferent access truly indifferent which would
help this particular use case. I'm not sure what type of existing code this
would break, but I'm interested to learn what issues there would be with
this feature. What do y'all think of this idea?
