That is, you güç create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?
