Steps to reproduce the issue: 1. Clone and open repository https://github.com/neko-kai/intellij-repro-Xsource3-wildcard-highlighting 2. Navigate to "src/main/main.scala" that contains the following: import distage.DIKey import izumi.distage.testkit.TestConfig.PriorAxisDIKeys object App extends App { val x = PriorAxisDIKeys.fromSet(Set.empty[DIKey]) println(x) } Expected result: No highlighted errors Actual result: Argument to ".fromSet" is highlighted as an error, expecting "Set[Any]" instead of "Set[DIKey]" (actual type is "Set[? ᐸ: DIKey]") Cause Intellij treats existentials named as "_$N" specially. When using "Xsource:3" and Scala 3 Wildcard Syntax (`?`), such existentials are named with "?$N" – the issue may be fixed if this pattern was treated similarly to underscore's pattern.…
