That is an important point.  But the point in a previous thread about
operators corresponding to metamethods __and, __or, __xor and __not,
which could be supplied for some objects (arrays were mentioned) fits
in very nicely with their mapping to bit.band, bit.bor, bit.xor and
bit.bnot.  The other bitwise operators (shifts and rotates) do not
appear to be as generally useful.
