is_letter

Compares against the values of <code>letters</code> (the English alphabet),
ignoring case.

Creates a new chars class which looks like a string but is actually
a vector of individual characters, making 'strings' iterable. This class
enables vector operations on 'strings' such as reverse, sort, head, and set
operations.
