LabelDefExtractor

abstract class LabelDefExtractor extends AnyRef

An extractor class to create and pattern match with syntax LabelDef(name, params, rhs).

This AST node does not have direct correspondence to Scala code. It is used for tailcalls and like. For example, while/do are desugared to label defs as follows:

while (cond) body ==> LabelDef($L, List(), if (cond) { body; L$() } else ())
do body while (cond) ==> LabelDef($L, List(), body; if (cond) L$() else ())
