Agreed, this would be a nice feature to have.

It's obviously a more dangerous operation than most, so a suitably
scary name ("resize_uninitialized_yes_yes_I_know_what_Im_doing")
might be called for...

Right now, I just use a wrapper class for the stored element type to
achieve this effect, but that's less flexible and can be awkward.
