What extra call? q{} gets compiled to a sub, so leave(enter()) was already present.

Furthermore — and my whole point — the subs now close over lexicals @short, @none and @long, whereas the q{} code used @main::short, @main::none and @main::long, all of which were empty. You could use our @short, etc as an alternative, but when I suggested that in the past, it seemed to confuse people.

Update: oh! I see the code is not compiled into a sub:

    if (ref $c eq 'CODE') {
    $subcode = "sub { for (1 .. $n) { local \$_; package $pack; &\$c; 
+} }";
        $subref  = eval $subcode;
    }
    else {
    $subcode = "sub { for (1 .. $n) { local \$_; package $pack; $c;} }
+";
        $subref  = _doeval($subcode);
    }

You'd think that would be mentioned somewhere prominant in the documentation. I can only find a mention in a footnote on another topic.
