Printing raw string stored in variable

Kernel.inspect has options to control this via Inspect.Opts:

• :charlists - when :as_charlists all lists will be printed as char
lists, non-printable elements will be escaped.
When :as_lists all lists will be printed as lists.

When the default :infer, the list will be printed as a charlist if it is
printable, otherwise as list.

As an example:

iex(6)> inspect [32,33,34], charlists: :as_lists
"[32, 33, 34]"
iex(7)> inspect [32,33,34]                      
"' !\"'"

You can tell IEx to default to this behaviour by:

hex> IEx.configure [inspect: [charlists: :as_lists]]
:ok
iex> [32,33,34]                                     
[32, 33, 34]
