Yeah this automates a part of analysis with sugar which is very easy to get
wrong.
If you are looking for a class template specialization and you want to get its
as-written arguments, then you have to deal with the fact that you might
encounter along the way a TST from an alias template (or builtin template) that
might be pointing to anything, even an `int`, so it's very easy to get mixed up
here.
