A Proposed Extension to C++: Inline Typedefs in C++

THE PROBLEM:

	You often cannot express complex types in C++ without resorting to 
typedef statements.   This is inconvenient for simple types such as a
function from void * to void *.  Requiring me to define things like
:+
#typedef  void *(FunctionPointerToPointer)(void *);
#typedef  int (*FunctionAnyToInt)(...);    
#typedef  int (*FunctionStringAnyToInt)(char *,...);    
:-
imposes the overhead on the reader of understanding an unnecessary and
rather boring naming convention.  



THE SOLUTION:

	Introduce a new keyword \t{inlinetypedef}.  It goes in inline
    type-expressions in exactly the same place that the defined identifier
    goes in typedef expressions:

:+

Point *centerOf(Shape *shape);
  
FunctionPointerToPointer f  = ((void *(inlinetypedef)(void *))) centerOf;
