/**
 * A Java problem.  What is the output of this function. Alternately
 * put, wheat is the final value of the variable k (and kk)?
 * This all depends on when exactly the ++ happens and if the timing
 * of the increment is affected by things like function calls.
 * 
 * All of this confusion is made passible by the fact that ++ is an
 * expression rather than a statement.
