abstract class CaseDefExtractor extends AnyRef
An extractor class to create and pattern match with syntax CaseDef(pat, guard, body).
This AST node corresponds to the following Scala code:
case pat if guard => body
If the guard is not present, the guard is set to EmptyTree.
If the body is not specified, the body is set to Literal(Constant(()))
