Can't edit my original reply anymore, but fair point, I've changed the keyword 'function' in the AST to a function return type instead. There's no error handling done yet to check whether the variable receiving the function return data matches the function return type, but it's on my todo list.

Then again in C it would work aswell if you type casted the types.

  const char *f()
  {
      return (const char*)123;
  }

  int main()
  {
      int i = (int)f();
      return 0;
  }
