</div></div>No.<br></blockquote><div><br>OK. I'd have preferred to have to avoid bloating the module symbol table with global symbols that will never be referenced but it's no big deal.<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
