Correct.

Except that my set of N widgets may include some number of "empty"
subforms, which are accepted.  Since D::FV doesn't have a
dependency_group_regexp (and indeed, I'm not really faulting it, that's
getting a bit extreme..), that is no longer easy to manage.

I haven't gone through that yet, but I have reached the conclusion that
I'm just running into the limits of CGI.

So I've discovered, but that's a good usage too, and one that I'm sure
to run into eventually (I use D::FV as an improtant element in an Online
Survey tool we've got here.  I was most pleased to discover the hash
form of dependencies, and I'm sure at some point they'll want us to do
something that will require the features you're looking for.  If I had
sufficient tuits...sigh.

I suspect I'll just package the data-twisting I do before passing to
D::FV into a more generic form.  I'll let everyone know when I come up
with.

Thanks for the various advice.
