Should'nt the dereference() in the policies return a const_reference
instead of a reference ?

I'm using a projection_iterator to navigate over a sequence and my
UnaryFunction returns a const reference. This results in a compiler
error (gcc-3.0.3).

Particular in the case of the projection_iterator, the 'function' is a
one way function (able to convert the real content to the iterator's
value_type and not vice-versa, thus the iterator can never be writeable)
and thus only a 'dereference() const' is possible returning a
const_reference IMHO ?
