Method/Sub Binding In Raku

Question

I'd like to find out if there is a way to bind a method and/or a sub to another method/sub name in Raku. I've seen how you can bind a variable to a method/sub, but that's not quite what I'm looking for. I know how to do it in Perl 5:

sub sub1 {
  print "sub1!\n";
}

*sub2 = \&sub1;

sub1(); # sub1!
sub2(); # sub1!

Answer 1

Actually, what you do with normal variables is pretty much exactly what you do with subs.

sub sub1 { say "sub1!" }

my &sub2 = &sub1;

sub1; # sub1!
sub2; # sub1!

You don't need to bind, actually, because subs are not containerized and &-sigiled variables don't have special handling for assignment like @ and %-sigiled variables. (If you do a .WHICH or .WHERE you can see that they point to the same place in memory).

Answer 2

@user0721090601 already gave the answer for subs. To do the same for methods is slightly more involved. Fortunately, there is a module in the ecosystem that makes that easier for you: Method::Also. This allows you to say:

use Method::Also;
# ...
method foo() is also<bar bazzy> {

And then you can call the .bar and .bazzy methods as well, and get the same result as calling the .foo method.
