  16. def formalTypes(formals: List[Global.Type], numArgs: 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 (numArgs - numFormals + 1) copies of its type is appended to the other formals. 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.

    [Martin] Can someone comment this please? I have no idea what it's for and the code is not exactly readable.

  36. object approximateAbstracts extends Global.TypeMap
  37. object instantiate extends Global.TypeMap

    Map every TypeVar to its constraint.inst field.

    Map every TypeVar to its constraint.inst field. throw a NoInstance exception if a NoType or WildcardType is encountered.
