I ran the following code in the IntelliJ REPL and was surprised that the output was a single line, not three.

for (num in listOf(1, 2, 3)) println(num)
123

Why isn't each element on its own line?

Woah, that's unexpected. Maybe a bug even

It's not a REPL think, it's a REPL in IntelliJ thing. The commandline REPL does not behave like that according to OP.

that's really just emitting two "\n" chars, isn't it?
