Expand description
Patterns are one of the more powerful ways to query text inside Harper, especially for beginners. They are a simplified abstraction over Expr.
Through the ExprLinter trait, they make it much easier to
build Harper rules.
See the page about SequenceExpr for a concrete example of their use.
