Re: [Pharo-project] why isEmptyOrNil is not defined in Object?

I would say for the same reason #isEmpty is not defined on Object, but only on Collection. #isEmptyOrNil is the equivalent of obj isNil or: [ obj isEmpty ] (which i find clearer and) which doesn't work on arbitrary objects either.

Hi guys

I'm puzzled and probably need food. but why  isEmptyOrNil is not defined in Object? because right now if a variable is '' or nil or something else I cannot use it.
