<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This conflicts with Matt's previous comment, that said it needed to be locked.
Looking at the code for the function (again), it doesn't look like it needs to be locked. Removed, unless anybody tells me otherwise.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Ideally, you would return a 400 error code if the failure is the user's fault (trying to set a function that does not exist), or 500 if it's an internal error (a function unexpectedly failed).
setvar_helper really doesn't distinguish the two, so I would err on the side of the user making the mistake and always return a 400 error code here.</pre>

I'm removing this error entirely (though, I'm adding a 400 for a missing variable arg).</pre>
