Well... implementations other than netbsd's sh seem to allow passing
parameters to a dot command:

valkyrie% cat y2
. ./y a b c d e
valkyrie% cat y
echo '$0 is '"$0"'; $@ is '"$@"
valkyrie% sh ./y2
$0 is ./y2; $@ is 
valkyrie% ksh ./y2
$0 is ./y2; $@ is a b c d e
valkyrie% bash ./y2
$0 is ./y2; $@ is a b c d e
valkyrie% zsh ./y2
$0 is ./y; $@ is a b c d e
valkyrie% 

although apparently only zsh changes $0.
