I think you need to define a TypeTrait that tells the ArrayHandle how to
do the conversion. For instance, see BasicTypeTraits<bool> in gconfmm.

I don't like ArrayHandle<> and friends, even though it is apparently the
correct way to present a container in an C++ API, and if I could break
the API then I would just force people to use either vector or list. But
for now, we need to be consistent.
