Should we also point out under which circumstances those functions behaviours are undefined?

What does it mean to say that *error* and *undefined* are "not even partial"? As far as I know, a function is either total or partial. If a function is not defined for any point, surely it is partial?

@Rcaetano I meant that they are not defined at any point --- the only purpose of these functions is to signal a pure exception. I don't know what the terminology is for this --- please update with the proper terminology if you know what it is :-)
