Re: [boost] [multi_index + mpl + bind] Regression?

Vladimir, I don't have my compiler handy right
now, but I think this is due to an overlook when
doing the adaptation to the new MPL. In particular,
the line 50 in boost/multi_index/detail/node_type.hpp:

typedef typename IndexSpecifierIterator::type index_specifier;

should be changed to
    
typedef typename mpl::deref<IndexSpecifierIterator>::type 
index_specifier;

(also, the corresponginf #include <boost/mp/defer.hpp>
must be inserted)
Could you please try this locally and report the results?
If the problem is solved, I'll commit something along this
line next Monday.

I don't know the rationale for having to use deref, since
I thought these two expressions are equivalent, but there
must be some difference, for Alexsey changed some of the
code in multi_index to do that when mergien the new MPL.
