boost::mpl::transform fails on boost::mpl::set in non-inserter form

[hack@…]

The following code does not compile with boost-1.48.0:

typedef boost::mpl::transform<
	boost::mpl::set<double,float>,
	boost::add_pointer<boost::mpl::_1>
>::type pointer_set;

It fails on a compile-time assert deeply into boost.mpl with "REQUESTED_PUSH_FRONT_SPECIALIZATION_FOR_SEQUENCE_DOES_NOT_EXIST". This makes sense, as boost::mpl::set is not a front extensible sequence. One can get this to work by using a custom inserter that utilises boost::mpl::insert instead of boost::mpl::push_front, or using a different sequence class in the output. However, I think boost::mpl::transform should either be able to detect a set properly, or the documentation should state that the non-inserter version of boost::mpl::transform requires a front extensible sequence.

The documentation for mpl::reverse should also be updated to say it applies to Front Extensible Sequences, too, because mpl::reverse exhibits this same issue.
