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 ]

yes this is what I did. I do not see the point of isEmptyOrNil just because people returns nil or '' while a default decent value should be returned.

(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.
