Word Lists For Atoms
The ~w sigil works similarly to Ruby's %w (word array notation). It
allows you to create a list of words (i.e. strings).
> ~w(one two three)
["one", "two", "three"]
It sets itself apart though with some modifiers. The default behavior
matches the s modifier (for strings).
> ~w(one two three)s
["one", "two", "three"]
Where it gets more interesting is with the a modifier allowing you to
create a list of atoms.
> ~w(one two three)a
[:one, :two, :three]
Note: there is a third modifier, c, for char lists.
> ~w(one two three)c
['one', 'two', 'three']
