Subject: [PATCH] Remove the warning about using erlang:raise/3

There is no good reason to say that erlang:raise/3 is only for
debugging. Here is an example where it can be extremely
useful:

try
    do_something(Args)
  catch Class:Error ->
    Stack = erlang:get_stacktrace(),
    io:format("Args: ~p\n", [Args]),
    erlang:raise(Class, Error, Stack)

That is, we can let it crash, but log additional useful
information before crashing.
