Thanks! Pretty sure you can get progressive versions of this type of behavior (where obj["field"] is equivalent to obj[:field] or obj.field) by using Ruby's HashWithIndifferentAccess and/or OpenStruct classes, but those are both obviously more obscure than something which is a built-in default language feature.
