If the function object advertises a return type via the result_type typedef, 
or if the function object is a function pointer or another entity with a 
fixed return type, result_of returns that type.

Otherwise, if a particular argument list results in an ill-formed 
expression, the application of result_of on that argument list is also 
ill-formed.

Do you have a specific scenario in mind?
