I know it's not iteration in the imperative sense (how could it be?),
but molding a template metaprogramming library into the STL concept
framework seems odd and unnatural to me.  I'm not a functional
programmer, but I do understand recursion and its elegance.

Bottom line: I look at Aleksey's (?) implementation of count_if
and I look at Andrei's implementation.  Guess which one is
easy to grasp.

Again, I probably haven't put in the effort required to fully
understand MPL (in fact I know I haven't).  But then, how can I
when the documentation is lacking?  This MPL2 branch seems to
have appeared out of nowhere (can someone provide that tag again?
I seem to have deleted the message that mentioned it).  Before
yesterday I thought mpl_development was the current MPL branch.
It's kinda hard to keep up.  :)

I do really want to see MPL in Boost.  I'd just like to have
some input as to what kind of MPL we get.
