Hey David. I had a response written to this quite a while ago, but I
realized tonight that I never posted it for some reason. In any case,
in addition to the solution Yariv suggested, I've found something else
to work reasonably well: wrap the longer section in an iolist. So,
your code above would actually look like this:
<% case Authenticated of
false -> "";
true ->
["<tr><td colspan=\"2\">",
do_something(),
"</td></tr>"]
end %>
Yeah, it kind of takes the HTML-likeness out of the thing, but for
short snippets, I've found it works pretty well.
