This interface describes how coloring is stopped and started for text
that knows how to color itself. It also describes how to query the
lexical and s-expression structure of the text.

The @scheme[pairs] argument is a list of different kinds of matching parens. The second

are three kinds of parens. Any token which has @scheme['begin] as its second
