> If you try to assign multiple variables from an iterator Groovy will skip every other value.
> Example:
> {code}
> final list = [1,2,3]
> final iter = list.iterator()
> final def (a,b,c) = list
> final def (d,e,f) = iter
> assert "$a $b $c" == "$d $e $f"
> {code}
> Result:
> {noformat}
> Assertion failed: 
> assert "$a $b $c" == "$d $e $f"
>          |  |  |  |    |  |  |
>          1  2  3  |    1  3  null
>                   false
> {noformat}
> The expected behavior is either that the assertion succeeds, or the assignment to (d,e,f) fails outright.
> If this is fixed it would also be nice if any Iterable could be used on the RHS.
