This differs from the problem statement, which has the argument reference the 
same instance as that through which the (instance) method is called.  The 
method that you show here is a candidate for 'static' scope as it does not 
depend on the state of 'this'.  In particular, there is no guarantee in this 
proposal that 't' or 'thing' point to the 'this' instance, nor to the same 
instance as each other.
