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"]
