Retrieve the expression substituted for this matcher from a previous successful match

<p>
Calling this on the root matcher is relatively useless, as it would simply return the
expression passed to {@link #match(PatternExpression)}. Instead, sub-matchers should be saved
in a variable, allowing their values to be retrieved. See {@link Context}, for an example.

@param results the previous match results
@return the substituted expression
