      Description

      Rather than having a special RangeExpression 0..5 we could just make .. an operator.

      Then the .. operator on numbers could create a range and we can use this operator to do a 'traverse' on other objects. E.g. we can use .. to be like // in XPath.

      e.g.

      node = builder.foo() {
      bar()

      { x("a") x("b") }

      }
      node..x

      would yield [ x("a"), x("b") ]

      We could also use .. to invoke methods on collections of objects too.

      node..x..name() would yield ["a", "b"]

          Seems as if this is implemented in the new ECMAScript4XML (E4X). I thing it would be nice to have this here.

          GPath expressions use '.' for this functionality now. So node.x yields [x("a"), x("b")]

          Syntax not required as GPath handles this use case.
