> Currently multiple-assignment is implemented using {{getAt(int)}}.  For types that support {{getAt(IntRange)}} it may be more efficient to use that operation.  For cases where {{getAt(int)}} is a terminal operation (aka streams) it may be the only way to go.
> Consider the following:
> {code:groovy}
> Set<String> set = ['foo','bar','baz']
> def (foo, bar, baz) = set // inefficient; requires 3 iterators and 6 calls to next
> Stream<String> = ['foo','bar','baz'].stream()
> def (foo, bar, baz) = stream // not possible because `getAt(int)` is terminal
> {code}
