/**
 * @assertion Execution of a do statement of the form do s while (e); proceeds as follows:
 * The statement {s} is executed. Then, the expression e is evaluated to an object o.
 * Then, o is then subjected to boolean conversion, producing an object r.
 * If r is false, execution of the do statement is complete.
 * If r is true, then the do statement is re-executed recursively.
 * @description Checks that the number of iterations is correct for various valid expressions.
