But I initialised the projection_iterator with a const_iterator over my
container and thus expected the reference type to be const T& but I now
see the result_type of the function is used to defined the
reference_type of the iterator_adaptor.

Anyway, I apparantly overlooked the const_projection_iterator and this
solves my problem.

BTW, should'nt it be a good idea to verify if the result_type of the
function is identical to the reference_type of the base iterator ?
