Let's consider these statements: ``` Seq(1, 2, 3, 4).map(x => x + x * 2) // (1) Seq(1, 2, 3, 4).reduce((x, y) = x*x + y*y) // (2) ``` Scala...
Here are two bugs that are triggered by -Ykind-polymorphism. Both can be reproduced with SBT 1.0.0 and following options: ```scala scalaOrganization in ThisBuild := "org.typelevel" scalaVersion in ThisBuild := "2.12.3-bin-typelevel-4"...

The combination of `-Yinduction-heuristics` and `updateOptions := updateOptions.value.withCachedResolution(true)` results in an error during `compileIncremental`: ``` MissingRequirementError: class scala.annotation.inductive in compiler mirror not found. ``` Steps to reproduce: * clone https://github.com/tek/tls_test...
