Sigils in Elixir

In Elixir, there's strings "hi" and charlists 'hi'.

You can also use the ~c sigil to denote a charlist -

~c"hi there"

There's also a word list sigil ~w which behaves similarly to %w in Ruby. It constructs a list of words -

~w(blue red green)
=> ["blue", "red", "green"]

Also worth mentioning, the ~r sigil for regexes -

"foo" =~ ~r"hashrocket"
=> false

"hashrocket" =~ ~r/hashrocket/
=> true

There's many other sigils in Phoenix and Elixir. Be sure to check out the docs!
