So, learning a new language, Elixir, and after
installing it (a breeze, way easier than ruby), I start up the Elixir
REPL, IEx, type a few bon mots and then I’m stuck trying to quit the
Fun stuff, but it did panic me a little as the normal things I tried
I don’t quite understand why Ctrl-C wasn’t working, perhaps because of
the prior two errors? I haven’t been able to reproduce it
subsequently, so even more likely I was just fatfingering the keyboard
and missing the Ctrl-C.
