Overloading regression in Scala 3 (with implicit conversion)

[unkarjedy]

similar to #14699

The following works in 2.13, but fails in Scala 3.

Compiler version

3.1.2

Minimized code

import scala.language.implicitConversions

trait StringShouldWrapperForVerb {
  def should(right: String): Unit = ???
  def should(right: => Unit): Unit = ???
}

object Example {
  implicit def convertToStringShouldWrapperForVerb(o: String): StringShouldWrapperForVerb = ???

  //ERROR
  "test 1" should {
  }
  
  //OK
  "test 2" should {
    ()
  }
  
  val s: StringShouldWrapperForVerb = ???
  s should {
    ()
  }

  s should {
  }
}

Scala 3 scastie
Scala 2 scastie

Output

None of the overloaded alternatives of method should in trait StringShouldWrapperForVerb with types
 (right: => Unit): Unit
 (right: String): Unit
match arguments (<nonsensical><notype></nonsensical>)

Expectation

No error, same as in Scala 2.13?

I accidently noticed this issue when upgrading tests for ScalaTest integration in IntelliJ to Scala 3 & ScalaTest 3.2.11.
(it's not critical to me, though)

Real example

lazy val scalatest_3_2_11 = project.settings(
  scalaVersion := "3.1.2",
  libraryDependencies ++= Seq(
    "org.scalatest" %% "scalatest" % "3.2.11"
  )
)

import org.scalatest._
import org.scalatest.wordspec._

class WordSpecTest extends AnyWordSpec {
  "empty 1" should {
    "ignore other tests" in {
      print(">>TEST: FAILED <<")
    }
  }
  
  "empty 2" should {
    //commented test body (for some reasons)
  }
}

This can happen when someone comments test body (for any reason)

This works on 3.1.3-RC2 so I guess it was fixed at the same time as #14699

[unkarjedy]

Indeed, thanks!

I thought that it was fixed in 3.1.2, cause I saw no error in the example from #14699
But turns out I just used the same file, and it showed the first error, hiding the error from the ticket =D
