def extractorFormalTypes(pos: Global.Position, resTp: Global.Type, nbSubPats: Int, unappSym: Global.Symbol, effectiveNbSubPats: Int): (List[Global.Type], List[Global.Type])

Returns (formals, formalsExpanded) where formalsExpanded are the expected types for the nbSubPats sub-patterns of an extractor pattern, of which the corresponding unapply[Seq] call is assumed to have result type resTp.
Returns (formals, formalsExpanded) where formalsExpanded are the expected types for the nbSubPats sub-patterns of an extractor pattern, of which the corresponding unapply[Seq] call is assumed to have result type resTp.
formals are the formal types before expanding a potential repeated parameter (must come last in formals, if at all)
nbSubPats
The number of arguments to the extractor pattern
effectiveNbSubPats
nbSubPats, unless there is one sub-pattern which, after unwrapping bind patterns, is a Tuple pattern, in which case it is the number of elements. Used to issue warnings about binding a TupleN to a single value.

Exceptions thrown
TypeError
when the unapply[Seq] definition is ill-typed

def formalTypes(formals: List[Global.Type], nargs: Int, removeByName: Boolean = true, removeRepeated: Boolean = true): List[Global.Type]

The formal parameter types corresponding to formals.
The formal parameter types corresponding to formals. If formals has a repeated last parameter, a list of (nargs - params.length + 1) copies of its type is returned. By-name types are replaced with their underlying type.
removeByName
allows keeping ByName parameters. Used in NamesDefaults.
removeRepeated
allows keeping repeated parameter (if there's one argument). Used in NamesDefaults.
