I went to take a look at Dotty at the suggested site [https://dotty.epfl.ch/] and the Features section of the homepage contains two broken links [http://dotty.epfl.ch/docs/reference/other-new-features/auto-parameter-tupling.html, http://dotty.epfl.ch/docs/reference/other-new-features/multiversal-equality.html].
It creates a poor initial impression of Dotty's maturity.
Hi, would there be a way, via the new export feature to achieve smthg like:
final class MyClass(a: String) { def f = println(a) }
trait MyTrait { def g = println("boo") }
val x = new MyClass("hello world")
class MixMyTrait[T](x: T) extends MyTrait { export x._ }
new MixMyTrait(x).f
|^^^^^^^^^^^^^^^^^^^
|value f is not a member of MixMyTrait[T]I tried with a ClassTag as well, but doesn't help
case class Point(x0: Int, x1: Int, x2: Int, x3: Int, x4: Int)
Point(1, 2, 3, 4, 5) match { case Point(x, rest: _*) if x > 0 => true; case _ => false }
^^^^^^^^^^^^^^^^^^
// Wrong number of argument patterns for Point; expected: (Int, Int, Int, Int, Int)

Ive started experimenting with Dotty in VSCode. Im really impressed by the library compatibility with Scala 2.x using withDottyCompat in build.sbt. I have been able to throw Typelevel libs into a Dotty project and so far (almost) everything "just works"...
.. but it seems like the IDE isn't reloading/reimporting build.sbt changes, as editor is complaining about missing library imports, while SBT CLI is fine. Is there a key-combo I should hit to trigger reimport of the SBT build?
