The following assertion currently does not work with Scala 3:

val exit = Exit.success(1)
assertTrue(exit.isSuccess)

Fails because Select.unique cannot decide between def isSuccess: Boolean on Exit and def isSuccess(implicit trace: Trace): Boolean on ZIO.

Tried Select.overloaded instead but that also fails saying the method has no overloads.

So the proposed workaround in case unique does not work tries to find the method in the direct type of the LHS and selects that.
