There are a number of things that could enhance BitArray's functionality:

* BitArray doesn't appear to have any way to set all bits to a given value
efficiently.

The D'ish way would be to provide an opSliceAssign(bool val) and then you could
do   bitarr[] = true;

* It should probably support other slice operations as well, at least the basic
opSlice, if not more general opSliceAssign.

* Also missing I think is a way to flip the bits in place.
If there were overloads for the numeric operators that did "broadcasting" then
that would take care of it, because then you could do  
    bitarr ^= true;
to flip all the bits.  By "broadcasting" I mean treat a single bool as if it
were a BitArray containing that same bool value repeated N times.
