<p>Gives a chance for the rule to do some pre-processing on the syntax tree.
|

One typical example is using <code>SwiftOperators</code> to “fold” the tree, resolving operators precedence.
|

This can also be used to skip validation in a given file.
|
||
By default, it just returns the file’s <code>syntaxTree</code>.</p>
