Lists are (sometimes) strings. \a is 7. Ergo, [7] == '\a'

Hi all --I'm getting a '\a' when trying to insert into an empty list. Doesn't appear to be expected behavior.

Hey
[7] == '\a'
Single quote strings are actually lists of characters, so when you have a list of numbers that can be treated as characters Elixir will print them as like so.
Cheers,
Louis
