How is the bare string creating better habits? The only time I've ever
been happy with bare strings having functionality[1] is in shell-like
languages (including REXX; the one time I built a REXX system in which
bare strings weren't executed as commands was a MUD, where command
handlers could use bare strings to send lines of text to the client,
and I wasn't happy with that - an explicit function would have been
better). I'd much rather teach a function that produces clean output
than depend on the REPL for Hello World. Now, depending on the REPL
for *expressions* is quite another thing.

>>> 1+2

That makes perfect sense! But it's using Python as a calculator, not
as a programming language. Python blurs the line a bit, but for
teaching programming, I'd use programming style even at the REPL:

>>> print("Hello, world!")
Hello, world!
