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']
