You can explicitly instantiate Foo for a given T template parameter with template class Foo;

As for batch instantiation, I don't think it is possible. Maybe with variadic templates it is possible to create an Instantiate class so something like Instantiate would instantiate the appropriate templates, but other than that, you have to resort to manual instantiation.
