Aside from what Mordengaard wrote, you would be able to do:

   vars["ac"] = this_object();
   vars["weight"] = "Hello World";
   vars["name"] = -1;
   vars["short"] = 0.0;

And the compiler wouldn't stop you when compiling the code because it has 
no idea that vars["ac"] should probably be an integer value, etc.

So you lose the compiler-enforced distinction between static, private and 
regular variables, you can run into conflicts between variables from 
different (inherited) programs, and you lose type information.

Cheers,

Erwin.
