You can use the head[2] sub to write it as

Also, on the

     $ReturnStr += $Line

If you're trying to concatenate a string, you should use the ~ instead
of the +, so it'd become

     $ReturnStr ~= $Line

@ReturnAry[ 0 .. @ReturnAry.elems - 3 ]  -> $Line
      { $ReturnStr ~= $Line ~ "\n"; }

[@ReturnAry.elems - 2] is "$?"

Thank you!
