They sure may, but why is it so horrible to you to document
to the users of your optimized libraries that certain
arguments to certain functions must be carefully
non-aliased?  That kind of restriction stopped nobody from
specifying a standard function that defines and returns a
static object (thus making more than one call to the
function a risky construct, at best...)
