Minimized code

//> using scala 3.nightly
package a

import language.experimental.captureChecking
import caps.*

class A extends SharedCapability:
  private var x = 0
  def f() = x += 1

object ObjA:
  val a: A^ = A()

object ObjB uses_init ObjA:
  val x = ObjA.a.f()

object ObjC uses ObjA:
  def x = ObjA.a.f()

Output

Running scala doc on this file hangs forever.
Removing ObjB and ObjC will resolve it.
