We currently call a lot of functions with the same list of types. To avoid forgetting any of them and to avoid manually generating cartesian products of types, this patch adds type_lists and utilities for it. Specifically, it adds

- `type_list` - This is just a list of types
- `concatenate` - This allows concatenating type_lists, types and combinations of both
- `wrap_list` - Wrap all types of a type list with a template type of alias
- `cartesian_product` - generates the cartesian product of two type lists
