The immediate thing that doesn't "work" is copying and pasting them
into drracket -- that only pastes the first frame.  The student was
also hoping to use it with 2htdp/image and 2htdp/universe to
automatically animate, which obviously won't work.

Probably, there's no bug here.

I'm not really clear what we should do with them. Count them as a
vector of images? Make BSL be an frtime derivative? Something in
between? (what?)
