I guess you refer to bottom page 27.
Anyway what we use for the fx type is not partial specialization, just
plain old function overloading and this is allowed.
The two points he makes is that you can not change the return type of a
function, mainly because it is not mangled. And you can not change
internal types unless it is reflected in the signature, my guess would
be again this is a problem of how names are mangled (don't have time to
check it). So for all practical purposes you are stuck with what
function overloading allows you to do.
kind regards,
gerrit
