sbt console tab completion broken after importing io.kjaer.compiletime._

[valencik]

To reproduce:

1. run sbt backendsJVM/console
2. once console has loaded, enter import io.kjaer.compiletime._
3. type 1. followed by the tab key (1, period, tab) to show completions on value 1

This results in the error pasted below, but with the likely interesting part here:

Toplevel definition <init> is defined in .../io/kjaer/compiletime/dependent$package.class and also in .../io/kjaer/compiletime/IndicesOf$package.class
One of these files should be removed from the classpath.

This is the only related commentary i could find upstream: scala/scala3#11546 (comment)

[valencik]

Update: This is an upstream dotty issue. I've opened the following: scala/scala3#11641

[EmergentOrder]

Thanks for reporting this. 3.0.0-RC2 is out now, and this issue looks resolved, but scalatest for RC2 isn't released yet. when that comes, will move to RC2 here

[EmergentOrder]

This is now fixed.
