That's probably because your professors thought you were more advanced than
other new Pythonistas, because you were CS students. If I were in their
shoes, I might chose a different approach depending on the level of the

It might. Would it affect doctests? Would it make indirect infinite
recursion more difficult to trace? Would it make me remember yet another
command line option or REPL option to turn on complete reprs? Would it
force me to explain yet another config setting to new programmers?

I think a beginner understands when they've printed something too big. I
see this happen frequently. They laugh, shake their heads, and retype
whatever they need to.

If they're using IDLE, they say, "OMG I crashed it!" then they close the
window or restart IDLE. I'd say it's more a problem in IDLE than in the
default REPL.
