Just out of curiosity, which of the Smalltalks that claim to be ANSI
compliant actually implement the above? A dead giveaway would probably
be Number>>#@- (except that according to ANSI this requires spaces, too,
right? right??? ;-) so can anyone confirm which Smalltalks out there
actually compile according to those rules? Briefly checking VW shows it
doesn't, neither does Squeak. What about others?
