    that

    The object with which this $coll should be compared

    returns

    true, if this $coll can possibly equal that, false otherwise. The test takes into consideration only the run-time types of objects but ignores their elements.

  34. def partition(p: (A) ⇒ Boolean): (Seq[A @scala.annotation.unchecked.uncheckedVariance], Seq[A @scala.annotation.unchecked.uncheckedVariance])

    A pair of, first, all elements that satisfy prediacte p and, second, all elements that do not. Interesting because it splits a collection in two.

    The default implementation provided here needs to traverse the collection twice. Strict collections have an overridden version of partition in Buildable, which requires only a single traversal.
