Using str() in a function.

Andrew Hoerner 
David --  Ah! Excellent. OK, that explains Dennis's function's output.
Print(str(X)) evaluates str(X), sending the usual str() output to the
console as a side effect, and then prints what str() returns, which is NULL. 
And invisible() prints NULL again, but we don't see NULL NULL, because the
second one is invisible. 

Still puzzled by the order of my output, though.
