In fact, in my -yet-another-list-implementation-, I used int_, bool_,
char_, opting for the shortest possible name. IMO, in its domain
these are the primitive types. I am not at all concerned about
confusion since it is in its own namespace and I assume that
clients of the library read the documentation (if any).
