ok. does this fixup happen also when $fd is used in an expression, like

$var(foo) = $fd;

if i write 

lookup_domain("$fd", "$fd");

the first $fd must be an avp, because lookup_domain expects an avp name
as first param and the second could be either a pvar or avp, but that
can be determined at fixup time.
