Thanks Peter,

Well, for some strange reason I do not see the wood for the trees in this
case.
I do not even thought about using std::count_if. ;)

Doesn't work either, that still produces the same errors. Nevertheless, the
above 
solution seems much more readable to me anyway, although I still would like
to know
if this could be also achieved by using boost::lambda in some way.
