Sorry, was not able to minimize, so there would be no dependency on scalamock.
This bug makes integration of scalamock with zio-test problematic.

lazy val root = (project in file("."))
  .settings(
    scalaVersion := "3.6.3",
    name := "zio-test-example",
    libraryDependencies ++= Seq(
      "dev.zio" %% "zio" % "2.1.16",
      "dev.zio" %% "zio-test" % "2.1.16" % Test,
      "org.scalamock" %% "scalamock-zio" % "7.3.0-RC4" % Test
    )
  )
import zio.*
import zio.test.*
import org.scalamock.stubs.ZIOStubs

trait IntService {
  def foo(clientId: String): Task[Boolean]
}


object MySpec extends ZIOSpecDefault, ZIOStubs {

  override def spec: Spec[TestEnvironment & Scope, Any] =
    suite("MySpec")(
      test("MyTest") {
        val intServiceStub = stub[IntService]
        for {
          _ <- stubbed(intServiceStub.foo).returnsZIO(_ => ZIO.succeed(true))
        } yield assertTrue(
          stubbed(intServiceStub.foo).times == 0
        )
      }
    )
}

It is strange, because if I change stubbed(intServiceStub.foo).times == 0 to stubbed(intServiceStub.foo).calls.isEmpty everything compiles just fine

Exception occurred while executing macro expansion.

Looks like it is due to this .tree call. Found similar issue in izumi-reflect.
