Presumably using declaration order as a means of prioritizing
which name wins was rejected as a design possibility in the case
of mixin templates which don't do this.
There is a strong parallel between name collisions between
multiple mixin template instantions in the same scope, and
muliple AliasThis declarations in the same scope: both bring an
arbitrary collection of names and their concomitant collisions
into that scope.
So presumably using declaration order as a means of prioritizing
which name wins in the case of AliasThis would be rejected for
the same reasons as for mixin templates.
