[Informative] `deep_symbolize_keys` broken in Rails 7 with `Mash` about hashie

[dblock]

We should probably raise in that case.

@DerekYu177 It would be awesome if you could turn this into a failing spec w/Rails 7 in hashie.

[DerekYu177]

Opened.

This appears to be issue in Rails 7 when using deep_transform_keys for Trash and so I'd assume Dash as well.

@aflansburg Do you think you could contribute an integration spec for Rails 7 similar to https://github.com/hashie/hashie/tree/master/spec/integration/rails? (maybe that should be called rails6)

[aflansburg]

@dblock can do - for what it's worth I was able to get around this by doing

hashie_thing.to_hash.deep_transform_keys { |key| # transfoms }

@dblock https://github.com/hashie/hashie/pull/569/files

Pending spec merged in #569, maybe someone wants to try and fix the issue?
