Of course, you could just as well say that you _never_ need to see
anything printed unless you ask for it. The first time I used the REPL I
was irritated by the fact that None wasn't printed. The reason that None
isn't printed is, of course, because Python has no distinction between a
function that returns None as a value and a function that doesn't return
a value.

The alternative is to make assignments special within the REPL, or even
turn it into something that looks less like a REPL and more like the
variable/expression list that some IDE debuggers have.
