[htmltmpl] how can I insert non-printing comments in templates?

[Puneet K. <pk...@ei...>]

While templates are supposed to be (almost) pure html, I want to insert 
comments in the templates (for my benefit... all those loops within 
loops get confusing after a while) that I don't want printed in the 
browser. Would be nice to have some kind of meta template comment tag 
that is stripped out while filling the templates on the server. 
Something like --


<!-- this is an html comment -->
<b>Some html here</b>

<<!-- this comment doesn't get printed in the html -->>
<<!-- start loop foo -->>
<tmpl_loop foo>

	<<!-- start loop bar -->>
	<tmpl_loop bar>

		<<!-- start loop baz -->>
		<tmpl_loop baz>

			<!-- today's blah gets printed in the browser -->
			<tmpl_var blah>

		</tmpl_loop baz>
		<<!-- end loop baz -->>

	</tmpl_loop bar>
	<<!-- end loop bar -->>

</tmpl_loop foo>
<<!-- end loop foo -->>
