[Moose-dev] InheritanceDefinition>>#superClass and InheritanceDefinition>>#subClass ??

Hello,

Really after one hour of thinking that somewhere there is a bug I found the selectors InheritanceDefinition>>superClass and InheritanceDefinition>>subClass

which are not accessors and they are different of:

InheritanceDefinition>>superclass and InheritanceDefinition>>subclass.

Could you please illustrate why we need the selectors #superClass and #subClass when we have the accessors #superclass and #subclass? Specially, could you explain why both return a group that will always contain one, and only one, element?

thanks, hani
