In particular, in the case of emulating a bit array, the distinction between
8-bit chars and 32-bit ints is less than that between chars and bits in the
first place.  If a 32-bit int is too wasteful, then so is an 8-bit char.

What this really implies is that, if bit arrays are ever supported, they won't
fit cleanly into the existing language and hence will probably not support all
the same features as "normal" arrays.
