[Pharo-dev] method usage example: annotation or comment?

Hi, I encountered some annotations in the form: < expr: (foo) result: bar > and some meta comments of the form: " foo >>> bar " I think both are aimed at providing examples of method usage for documentation, non regression testing, etc... I note that the former is requiring a literal result, which is quite limiting (1/3) is not a literal for example, 0@0 neither... IMO it should be extended for handling any valid expression. But that still makes two different ways of expressing the same intent. So what's the canonical one?
