[boost] question regarding Specialized Adaptors

I am working on a problem for which the most natural
solution is to derive from the boost::transform_iterator.

Unfortunately, it does not seem possible to do this.

The transform iterator does not include a derived
class in its list of parameters as it would need in
order to invoke most derived functions.

Is there any reason why the design prohibits
derivation?  Does anyone have any suggestion
on how to get the same effect?

I believe that this observation applies to all the
other specialized adaptors as well.
