==QUESTION - Page 8 says "In some languages, all methods are multimethods." I believe that Java is one of these. Is that right and what are some others? (This is really just curiousity.) ==/
Doesn't C++ work this way? Also I believe Pike allows overloading of methods by default.
==QUESTION - Given the following code, what is called by $ride.current_speed()?
class Vehicle { my $speed; method current_speed() { return $speed; } method set_speed($n) { $speed = $n; } }
class Car { submethod current_speed() { print SUPER.current_speed(); return SUPER.current_speed(); } }
class A6 { }
my $ride = new A6; # Perl with German engineering??? $ride.set_speed(60); # Calls Vehicle.set_speed() print $ride.current_speed(); # Calls what?
Unless this is more complicated than I think, Car's current_speed() is called.
That said, a minor nitpick is that you'd want something more like
class Vehicle { ... }
class Car is Vehicle { ... }
class A6 is Car { ... }
