This page has instructions on how succeed can return a value, but we don't demonstate that.

I don't know if we could show it succinctly without defining a sub

sub use-succeed() {
  given 42 {
    when Int {
        # say "Int";
        succeed "Found";
        say "never this!";
    }
    when 42 { say 42 }
    default { say "dunno?" }
  }
}

say use-succeed();

Or using do given, perhaps. Like my $value = do given { ... }

Yep. Just prepend a say do in front of the existing example in the doc:

say do given 42 {
    when Int {
        say "Int";
        succeed "Found";
        say "never this!";
    }
    when 42 { say 42 }
    default { say "dunno?" }
}
# OUTPUT: «Int␤Found␤»
