I know how I can avoid this issue. :-) I don't know is I should avoid it. :) Also, I can't avoid it so ease - I need to do s/// in some complex template, and I wish to detect errors in this template. Example with "qwe" can be converted to simple m//, but not my real task. My real task can be converted to something like: 
while (1) {
    $tmpl =~ /\G(...)/gcs  && do {
       if ($1 eq "w") {
           croak "w is bad";
       } else {
           $result .= process_template($1);
       }
    }
 || $tmpl =~ /\G(...)/gcs  && do {
       ...do.something.else...
    }
 || last;
}

You see, it's too complex to replace current single-line s/// just to be able to croak() on errors. :(
