Could I suggest adding convenience versions of these to boost?
For my own code I have a make_key_iterator and make_data_iterator
that are based on the iterator adaptors library (although they
don't use projection_iterator currently). They are quite handy
for working with std::map. Perhaps better names for these might
be make_1st_iterator and make_2nd_iterator.
Another iterator that is useful is make_indexed_iterator, which
does for Boost tuples what the above do for pairs.
where x.begin() is an iterator over a container of tuples.
This makes an iterator that presents the element at the
specified index of the tuples. I haven't used this one as
much because I don't (yet) use tuples much, and it could
probably use a better name :-).
