From c26a8db067e4f04ef959bb9a8402fa3e931c3cd7 Mon Sep 17 00:00:00 2001 From: Paul Phillips Date: Mon, 11 Feb 2013 08:53:14 -0800 Subject: Maintenance of Predef. 1) Deprecates much of Predef and scala.Console, especially: - the read* methods (see below) - the set{Out,Err,In} methods (see SI-4793) 2) Removed long-deprecated: - Predef#exit - Predef#error should have gone, but could not due to sbt At least the whole source base has now been future-proofed against the eventual removal of Predef#error. The low justification for the read* methods should be readily apparent: they are little used and have no call to be in global namespace, especially given their weird ad hoc semantics and unreasonably tempting names such as readBoolean(). 3) Segregated the deprecated elements in Predef from the part which still thrives. 4) Converted all the standard Predef implicits into implicit classes, value classes where possible: - ArrowAssoc, Ensuring, StringFormat, StringAdd, RichException (value) - SeqCharSequence, ArrayCharSequence (non-value) Non-implicit deprecated stubs prop up the names of the formerly converting methods. --- test/files/run/genericValueClass.scala | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'test/files/run/genericValueClass.scala') diff --git a/test/files/run/genericValueClass.scala b/test/files/run/genericValueClass.scala index 68162bb685..768e1f86a5 100644 --- a/test/files/run/genericValueClass.scala +++ b/test/files/run/genericValueClass.scala @@ -1,11 +1,12 @@ -final class ArrowAssoc[A](val __leftOfArrow: A) extends AnyVal { - @inline def -> [B](y: B): Tuple2[A, B] = Tuple2(__leftOfArrow, y) - def →[B](y: B): Tuple2[A, B] = ->(y) -} object Test extends App { + class ArrowAssocClass[A](val __leftOfArrow: A) extends AnyVal { + @inline def -> [B](y: B): Tuple2[A, B] = Tuple2(__leftOfArrow, y) + def →[B](y: B): Tuple2[A, B] = ->(y) + } + { - @inline implicit def any2ArrowAssoc[A](x: A): ArrowAssoc[A] = new ArrowAssoc(x) + @inline implicit def ArrowAssoc[A](x: A): ArrowAssocClass[A] = new ArrowAssocClass(x) val x = 1 -> "abc" println(x) } -- cgit v1.2.3
