why don't we just make *small* hierarchy of exceptions, all derived from
"socket_error" derived from "std::runtime_error" ? I hope that main LWG
objection was agains large number of exception classes, and I feel that
20 might be bit too many. Here "too many" means : it might be difficult
to define (and use correctly) them, assuming each exception class has
different meaning.

Another point: currently C++ standard defines only small set of
exception. I can perfectly understand Committee objections against
extending this hierarchy with many exception classes, specific to few
problem domains. Maybe defining namespaces (specifit to these domains)
inside std namespace, or defining exception classes inside other (domain
specific) classes could dismiss *some* objections (while rising others),
that's just my blind guess.
