Rails - May 2006 - Beware of HashWithIndifferentAccess#symbolize_keys!

Hi,

I just posted a patch tot he rails trac for a bug we found where
running symbolize_keys! on a HashWithIndifferentAccess will delete all
items from the hash. Please make sure you either never call
symbolize_keys! (or to_options! which just alias it) on a
HashWithIndifferentAccess, or apply the path attached from the ticket
at: http://dev.rubyonrails.org/ticket/5076

I also posted a much longer explanation in my blog at:
http://devblog.famundo.com/articles/2006/05/13/beware-of-hashwithindifferentaccess-symbolize_keys

Please note that symbolize_keys (without the ! at the end) works as designed.

Bye,

Guy.
