[boost] [bind][function_types] Why do bind objects not have an ::arity, ... interface ?

Hi,

I want to use a partial template specialisation which is selected on basis of 
the arity of a bind function object type. Event more, I'd like to access 
the ::arg1_type, etc types of a bind object type. Why is this not part of the 
boost::bind or lambda::bind interface ?

I thought solving it with the (to be accepted) 
function_types::function_type_arity<BoundType>::type::value, but the latest 
version of function_types does not 'support' inspection of bound object 
types.

Other library writers must have felt a need for this interface as well ? Or am 
I missing something ?

With kind regards,
Peter Soetens
