From 130e9a20755d512b47ca0fe41d8dfc3f6879cf86 Mon Sep 17 00:00:00 2001 From: Martin Odersky Date: Tue, 27 Jan 2015 11:13:54 +0100 Subject: Use normnalized type to report type errors. Without it, we get strange error messages like found: (implicit X)Y requred: Z when the problem is really that Y is not a subtype of Z. --- tests/pending/pos/t3152.scala | 20 -------------------- 1 file changed, 20 deletions(-) delete mode 100644 tests/pending/pos/t3152.scala (limited to 'tests/pending/pos/t3152.scala') diff --git a/tests/pending/pos/t3152.scala b/tests/pending/pos/t3152.scala deleted file mode 100644 index 3d1dcbd6f..000000000 --- a/tests/pending/pos/t3152.scala +++ /dev/null @@ -1,20 +0,0 @@ -trait Applicative[M[_]] - -sealed trait MA[M[_], A] { - def sequence[N[_], B](implicit a: A <:< N[B], n: Applicative[N]): N[M[B]] = sys.error("stub") - // def sequence3[N[_], B]()(implicit a: A <:< N[B], n: Applicative[N]): N[M[B]] = sys.error("stub") -} - -object test { - implicit def ListMA[A](l: List[A]): MA[List, A] = sys.error("stub") - implicit val ao: Applicative[Option] = sys.error("stub") - - /* This compiles OK: - (Nil: List[Option[Int]]).sequence3(): Option[List[Int]] - */ - - // BUG: error: immutable is not an enclosing class - // !!!
