Hi there,
I've been looking around to see if there's been any discussion of
introducing functional programming-style pattern matching for method/
function dispatch. Could someone point me to any such discussions?
I've seen that perl6 is taking on a lot of ideas from the functional
world (lazy evaluation for instance). With multi-method dispatch on
the agenda pattern matching seems inevitable but I haven't been able
to find information about this or any related discussions.
This is a contrived example of what I'm referring to:
sub traverse([Leaf $a]) {
# do something
}
sub traverse([Tree $left, Tree $right]) {
traverse($left);
traverse($right);
}
my $t = Tree(...);
traverse($t);
---
Many thanks!
