I suppose that might be true, depending on your definition of "work
properly."  There's no such thing as "working properly without
exceptions" if the library was coded for use with exceptions and you
really need a recoverable response to, say, resource exhaustion.

That said, "libraries should generally use BOOST_THROW_EXCEPTION" is a
good rule for Boost, and I wouldn't mind having something like it in
the inspect tests, provided that libraries with a legitimate reason
not to use it can be registered as exceptions to the rule.
