Hi,

Thanks for your answer...

To make that point clear, it is only required for static type  
checking of arguments and return types without having to use more  
than two template parameters. If you want to say it is not desirable  
for performance, I think deriving from std::unary_function costs  
nothing (since unary_function's only declare typedef's for return and  
argument types, there is not impact on calling the functor). The  
problem is that somehow I want the user to be explicit about those  
types.

I am of course open to any propositions to avoid deriving from  
std::unary_function that does not require a large template argument  
list.

All the best,

Franck
