Retry in Scala adaptor is ambiguous

[axel22]

The retry overload leads to ambiguities:

object Test extends App {
  import rx.scala.lang._
  (null: Observable[String]).retry(3)
}

both method retry in trait Observable of type => rx.lang.scala.Observable[String]
and  method retry in trait Observable of type (retryCount: Int)rx.lang.scala.Observable[String]
match argument types (Int)
   (null: Observable[String]).retry(3)

The problem is that there are two interpretations for o.retry(3): o.retry(retryCount: Int) or o.retry.apply(3).

[zsxwing]

Maybe we should remove apply method from trait Observable, considering it's likely to cause such ambiguities without careful attention.

Yes, I'd vote for removing def apply(index: Int): Observable[T], since it's probably not used that often, and elementAt is a better, more explicit name.

Thanks @samuelgruetter for weighing in. Based on the two of you agreeing, I'll merge that change.

[headinthebox]

Agree with @samuelgruetter .

[benjchristensen]

Closed as I believe the fix was merged.
