I'm probably late to the party with this reply. The primary reason for not changing this is that it would be incorrect. It comes down to intrinsic versus extrinsic meaning. A multiple operator has an intrinsic meaning: it means multiple. But a message name does not have intrinsic meaning (other than it is a good idea to have the name represent what it does). The meaning of a message is determined by the receiver. e.g. if PetitParser defines #* to mean "0 or more repetitions", what happens when someone has decided that it should be evaluated before #+? Message sending precedence can only be defined in terms of the type of message: unary, binary (or infix), and keyword, since the interpretation of the message is the receiver's responsibility, not the compiler's. -- View this message in context: http://forum.world.st/about-tp4764892p4765070.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
