Well theoretically we could have a 'remove_member_pointer' as well. 
Unfortunately it's not easily implementable without running into a lot 
of compiler-specific trouble.

The Boost CVS/SVN contains a library that is dedicated to deal with this 
trouble. See

     $(BOOST_ROOT)/libs/function_types/docs/html/index.html

it should contain easily readable traits for all the use cases you 
mentioned in this thread.
