Ad hock exceptions are not documented well enough.

[van-de-bugger]

Problem or new feature

Look at Ad hock exceptions, and the next section, Typed exceptions: Ad hock exceptions are contrasted to Typed exceptions. A novice reader might get the impression that these are two different kinds of exceptions.

Suggestions

It would be nice to say that die "message" is actually throws a typed exception of X::AdHock type.
