Hello, i know that we're already having #deprecated: , #deprecated: on: in: etc but one thing what i think useful about annotations that it is a way to indicate that method is deprecated without showing a warning. The problem with using messages, that if you deprecate something which used quite often by code, you will be spammed with deprecation warnings all the time. So, i think that in addition to messages, we can use these annotations, to indicate deprecated methods, in places where showing warning(s) are not feasible (for instance you cannot deprecate Deprecation>>showWarning, because it will lead to infinite recurtion) There could be variations in same way as with messages: <deprecated> <deprecated: '...' on: '..' in: '..'> etc. What you think? -- Best regards, Igor Stasenko AKA sig.
