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,
almost ... it _returns_ NULL ... without printing
but we don't see NULL NULL, because the
second one is invisible.
Still puzzled by the order of my output, though.
Dalgaard's explanation didn't work for you?
