### Type Members

1. #### final case class Aligned(patterns: Patterns, extractor: Extractor) extends Product with Serializable

   If elementArity is.

2. #### final case class Extractor(whole: Type, fixed: List[Type], repeated: Repeated) extends Product with Serializable

   An 'extractor' can be a case class or an unapply or unapplySeq method.

3. #### final case class Patterns(fixed: List[Pattern], star: Pattern) extends Product with Serializable

   Definition Classes
     PatternExpander

4. #### sealed case class Repeated(sequenceType: Type, elementType: Type, repeatedType: Type) extends Product with Serializable

   It's not optimal that we're carrying both sequence and repeated type here, but the implementation requires more unraveling before it can be avoided.

5. #### final case class TypedPat(pat: Pattern, tpe: Type) extends Product with Serializable

     PatternExpander

4. #### def NoPattern: Global.EmptyTree.type

   You'll note we're not inside the cake.

   You'll note we're not inside the cake. "Pattern" and "Type" are arbitrary types here, and NoPattern and NoType arbitrary values.

9. #### def applyMethodTypes(method: Global.Type): Extractor

   In this case we are basing the pattern expansion on a case class constructor.

   In this case we are basing the pattern expansion on a case class constructor. The argument is the MethodType carried by the primary constructor.

    Converts a T => (A, B, C) extractor to a T => ((A, B, CC)) extractor.

29. #### def unapplyMethodTypes(method: Global.Type, isSeq: Boolean): Extractor

    In this case, expansion is based on an unapply or unapplySeq method.

    In this case, expansion is based on an unapply or unapplySeq method. Unfortunately the MethodType does not carry the information of whether it was unapplySeq, so we have to funnel that information in separately.
