And, of course, all those lovely Unix programs that produce output on
stdout, they're full of code smell too, right? I don't care what
someone's background is; console output is *not* code smell.

Anyway, all you're doing is relying on the magic of interactive mode
to call repr() and print() for you.

When you start a script, you have a consistent environment - an empty
one. When you write a series of commands in the interactive
interpreter, the environment for each one depends on all the preceding
commands. So when you have a problem, you might have to copy and paste
the entire interpreter session, rather than just the one command.
