> Wow, I just skimmed the messages section in the blue book and you're right.�� I think this is an omission and that it should be specified that keyword message receiver and arguments are evaluated strictly left-to-right.�� I don't know of a Smalltalk implementation that doesn't evaluate in this order.
This doesn't sound right.�� I don't know whether I can dig out a
reference quickly or not, but I learned that precedence *within* the [
unary -> binary -> keyword ] is actually right to left, not left to
right.
�� a := b := c := d := 4
executes right-to-left.�� Other than humans generally read from
left-to-right, are there other reasons it should run left-to-right in
other contexts?
