=============== Diff against Collections-mt.919 ===============
Item was added: + ----- Method: Symbol>>isMessageSelector (in category 'testing') ----- + isMessageSelector + "Answer if the receiver is a valid message selector. This method is not perfect. + The compiler does allow all caps to be selectors but these are not included. + If AllowUnderscoreSelectors is true then _ is a valid selector but this will be excluded + also. But it is IMO more useful to exclude class names and hence exclude some rarely + used selectors than to erroneously identify class names as message selectors." + + ^Scanner isMessageSelector: self!
