Objects, TWEAK and return

[mimosinnet]

Hi,

When working with this week challenge for the PerlWeeklyChallenge
<https://perlweeklychallenge.org/>, I noticed this behaviour with TWEAK:

*This does not work:*
  submethod TWEAK {
    $!filelist.lines».split(',').map( -> ($a, $b) { @!show.push: ( $a, $b
)  });
  }

*This works:*
  submethod TWEAK {
    $!filelist.lines».split(',').map( -> ($a, $b) { @!show.push: ( $a, $b
)  });
    return;
  }

It also works with other commands instead of 'return' (like assigning a
value to a variable). From the examples in the documentation, I am not
certain this is the expected behaviour.

Thanks for this extraordinary language,

Joan


P.S: This is the context where the command appears.  Apologies for the
messy-Raku,
