Since functor applications are currently not inlined, the generated
code for the functor body has no way of seeing that its dealing with
an all-floats record. Hence the record will contain boxed floats.

I don't think this is documented anywhere, since this is an
implementation detail that (though unlikely) might even change in the
future.
