Ran into a ranges that refuse to turn into a list. For example the one in line 2.
iex(1)> Enum.to_list(27..77//4)
[27, 31, 35, 39, 43, 47, 51, 55, 59, 63, 67, 71, 75]
iex(2)> Enum.to_list(27..77//5)
'\e %*/49>CHM'
Line 1 gives expected list. Line 2 puzzles me.
Any explanations you can think of? Thank you.

It’s a special type of list called a charlist, a list of integers where all the integers are valid code points. The default
inspectbehavior is to represent such a list as the more “human readable” charlist. You can use thecharlists: falseoption to inspect it as a list of integers.You can configure the shell to do this by default globally or for certain projects.

Thank you. I have some reading to do, I see.

This issue comes up every other week or so on elixir forum, don’t worry. Probably the only way it goes away is if in a future version of elixir they get rid of list-encoding Erlang strings with single quotes, but that’s unlikely to happen unless Erlang makes a massive push to deprecate charlist first.
