Hi to all !

I have only one (and maybe a stupid ?) question:
Do you have a need for an general data type (something like the "Object" in
Java) ?

Currently the only thing I see this could be used is in a function that has
no parameters but still needs to return different kind of types (template is
not a solution here...)

Example:

Object    f(void);    // Function overloading is not possible if only the
return value changes
                            // int f(void), short f(void), etc... are not
possible

// The following would be possible...
int    x = f();
long    y = f();
// So would this...
int    x = 10;
int    y = 20;
Object    tmp;
tmp = x;
x = y;
y = tmp;    // Now, x has 20 & y has 10

"No matter how many times you fail you will success in the end..."
