bind() in the sense to get the address. with the address I can store new values in the variable.

get() should not be provided

let us keep the library  simple - chains of coroutiens will causes many problems

references are pointers == addresses - in the case I get the address of the pointer and store tat this place the address of the new value

caller.bind(x); // get address of the reference of x which contains the address of i
caller.yield(); // in this call I store the address of j at the address of reference of x.
