 An alternative approach is the development of a new REPL that actually compiles

 **Tasks:**
   * Add a simple TinyCC based REPL for Nim.
-  * Ensure that global state (that is: state stored in global variables) is kept during recompilations of the generated C code. This means the C codegen needs to emit some kind of getters and setters for global variable access.
