One thing I wish you could do with inline functions is declare global
variables with a name passed as an argument.  For example, with #define
you can do the following:

typedef enum { Type1,Type2,Type3 } DataType;

class Data
{
	DataType	type;
	int		value;

	...
}

#define	MakeOrange(name,v)	Data	name = { Type1, v }
#define	MakeApple(name,v)	Data	name = { Type2, v }

MakeOrange(fruit1,100);
MakeApple(fruit2,200);

How could you do this with an inline function?  (If someone says,
"Use a constructor!" you've missed the point...)
