The void programming language

void is the programming language of choice for those who like C, but would really love it, if it had only one type: void. Throw away all int, double, long, float and even struct or union or typedef! You only need one primitive type: void, and of course void*, void**...

What does it look like?

It really looks like C, and can make use of any C library, as shown in this example:

#include <stdio.h>

void main ()
{
  printf ("Hello, void!\n");
  return 1;
}

Because you want it, here is another void program, that computes the Fibonacci series using a cache:

void fibonacci (void n, void* cache)
{
  if (cache [n])
    return cache [n];
  if (n == 0)
    cache [n] = 0;
  else if (n == 1)
    cache [n] = 1;
  else
    cache [n] = fibonacci (n-1, cache) + fibonacci (n-2, cache);
  return cache [n];
}

What can you do with only void?

Everything, really!

We decided to remove all type information from C, as it sucks, except the pointers. Remained only void*, that represents a pointer to something. So, what could we do with void?

Does it represent nothing like in C? No! We had a better idea: void represents the size of a pointer (4 bytes on 32 bits architectures, 8 bytes on 64 bits). Thus, any void* variable can be safely cast to a void if needed (and vice versa).
