<br />
How does that stack? How would I return two {ewc}s? Like this?:
<br />
<br />
{response,
<br />
[{phased_vars,
<br />
[{title, "foo"},
<br />
{meta, "bar"}],
<br />
{body, [{ewc, navbar, [A]}
<br />
{ewc, cookies, [A, cookies:find()]}]}]}.
<br />
<br />
It looks good though; if I'm returning phased values like that, I'm
<br />
probably setting headers and whatnot, since I'm probably the initial
<br />
{ewc}. The only problem is that only initial {ewc}s can do it, not
<br />
nested ones (unless there are many levels of {phased,ewc...}). That's
<br />
fine for my purposes, but I don't know about most people.

<br />
This limitation seems resonable to me too. The main need for the
<br />
phased_vars feature is being able to set title, headers, etc, and
<br />
those are for the most part determined by the top level ewc, not its
<br />
subcomponents. If at some point we realize this is insufficient we can
<br />
do the work to remove this limitation, but for now I think it strikes
<br />
the best balance between features and ease of implementation.
