   Extend the argument list `givenArgs` with default arguments.

   Extend the argument list `givenArgs` with default arguments. Defaults are added as named arguments calling the corresponding default getter.

   Returns the extended arg list and missing parameters if any.

    Returns the parameter symbols of an invocation expression that are not defined by the list of arguments.

    args

      The list of arguments

    params

    Removes name assignments from args. Additionally, returns an array mapping argument indices from call-site-order to definition-site-order.

    Verifies that names are not specified twice, and positional args don't appear after named ones.

31.  def transformNamedApplication(typer: Analyzer.Typer, mode: Mode, pt: Global.Type)(tree: Global.Tree, argPos: (Int) => Int): Global.Tree

    Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect.

    Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect. If tree has the form Apply(fun, args) first the function "fun" (which might be an application itself!) is transformed into a block of the form { val qual$1 = qualifier_of_fun val x$1 = arg_1_of_fun ... val x$n = arg_n_of_fun qual$1.fun[targs](x$1, ...)...(..., x$n) } then for each argument in args, a value is created and entered into the block. finally the application expression of the block is updated. { val qual$1 = .. ... val x$n = ... > val qual$n+1 = arg(1) > ... > val qual$n+m = arg(m) > qual$1.fun[targs](x$1, ...)...(..., x$n)(x$n+1, ..., x$n+m) }

    typer

      the typer calling this method; this method calls typer.doTypedApply

    mode

      the mode to use for calling typer.doTypedApply

    pt

      the expected type for calling typer.doTypedApply

    tree

      the function application tree

    argPos

      a function mapping arguments from their current position to the position specified by the method type. example: def foo(a: Int, b: String) foo(b = "1", a = 2) calls transformNamedApplication(Apply(foo, List("1", 2), { 0 => 1, 1 => 0 })

    returns

      the transformed application (a Block) together with the NamedApplyInfo. if isNamedApplyBlock(tree), returns the existing context.namedApplyBlockInfo

### Deprecated Value Members

1.  def formatted(fmtstr: String): String

     This member is added by an implicit conversion from NamesDefaults toStringFormat[NamesDefaults] performed by method StringFormat in scala.Predef.
   Definition Classes
     StringFormat
   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

2.  def →[B](y: B): (NamesDefaults, B)
   Implicit
     This member is added by an implicit conversion from NamesDefaults toArrowAssoc[NamesDefaults] performed by method ArrowAssoc in scala.Predef.
   Definition Classes
     ArrowAssoc
   Annotations
     @deprecated
   Deprecated

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
