Prelude

I stand corrected, Eily and hippo are right, the sub can only see closed over variables, I didn't try the code, mea culpa

update end

I don't understand your question, what is natively supposed to mean?

Both func return the same $x.

$y = $myscalar; is the only important but non effective difference.

update getter

the straightforward way to implement this is an exported getter

sub get_myscalar {
  return $myscalar
}

If you really have too many individual lexicals to be handled by getters, you probably want to hold them in a hash instead.

update %exported_lex

my %exported_lex ={
   myscalar  => \$myscalar,
   myscalar2 => \$myscalar2,
}

sub get_lex_ref {
   return $exported_lex{$_[0]}
}

sub get_lex_val {
   return ${$exported_lex{$_[0]}}
}
