A proof of concept for a simple serialization technique. All changes to a structure are automatically propogated into all macro expansions, making for near zero maintenance programming. The format of serialization can be easily changed due to the nature of scanf scansets. Error checking can be implemented with similar macro expansion techniques without much of a hassle.

To Use:
Declare a struct in a header, do not use include protection. Declare struct with the following macros:

_NAME( )
_END( )


typedef struct SomeStruct
  double x;
  string t;
} SomeStruct;

Would be:

_NAME( SomeStruct )
_MEMBER( double, x )
_MEMBER( string, t )
_END( SomeStruct )

Then use this file to fill out macros within:

See MyObject.c and MyObject.h for a clear example.

There isn't any robust error checking. Member names and type names can be used to assert that serialization is behaving as intended, as well as to assert that the file format is correct.
