I need help with ~~m/

[ToddAndMargo via perl6-users]

Hi All,

rakudo-pkg-2020.12-01.x86_64

Why does this work?

> $x = "1.33.222.4";
1.33.222.4
> $x ~~ m/ (<:N>+) [.] (<:N>+) [.] (<:N>+) [.] (<:N>+) /;
｢1.33.222.4｣
 0 => ｢1｣
 1 => ｢33｣
 2 => ｢222｣
 3 => ｢4｣



But this does not?
   --> Why the wrong number in $2?
   --> Why no Nil for $3?

> $x = "1.33.222";
1.33.222
> $x ~~ m/ (<:N>+) [.] (<:N>+) [.] (<:N>+) [.] (<:N>+) /;
｢1.33.222｣
 0 => ｢1｣
 1 => ｢33｣
 2 => ｢2｣
 3 => ｢2｣


Yours in confusion,
