It is of course always "possible", after all its a mere matter of programming :)
And of course an instantiated class template is just a type, but what
is the name of std::vector<int> and std::vector<A> so it can be looked

Good point, the FT-Plugin API needs functions for goto declaration and
goto definition. Unlike TM, the plugin can take language and scope
rules into account when it answers, so you get the right declaration,
continuing the theme above, where would you go to find the declaration
of std::vector<int> ?
Certainly not the line:
thats the declaration of `list_of_ints` but thats the only place that
`std::vector<int>` exists in the code.

Only if your query plugin queries the FT plugin.
