[boost] [uuid] Confusing uuid_class example in documentation

Subject: [boost] [uuid] Confusing uuid_class example in documentation

http://beta.boost.org/doc/libs/1_42_0/libs/uuid/uuid.html#POD%20Efficien
cies includes some example code for making a uuid_class from the struct
uuid POD.

I was confused to see the example uuid_class both derives from
boost::uuids::uuid *and* provides operator boost::uuids::uuid() [const].

Aren't the conversion operators unnecessary, as a conversion function is
never called to convert an object to a base class of that type (by
12.3.2 [class.conv.fct])?

In fact the source file that the documentation references (e.g. at
https://svn.boost.org/trac/boost/browser/tags/release/Boost_1_43_0_beta1
/libs/uuid/test/test_uuid_class.cpp) doesn't include the conversion
operators. I think the documentation should be updated to match.

Cheers,
Gareth
