I am not sure if a-b at c-d syntax should be supported. (a-b)@(c-d) is supported and already working. It looks like a-b is only planned to use without @ and the usage a-b at c-d, like 1-2 at 4-5 implies to me: 1 -> 4 2 -> 5 but it doesn't work that way, it is always grouped after @, like it has parenthesis, what it does is: 1 -> 4,5 2 -> 4,5 Even a-b at c is not working, but as I said if @ will be used, using grouping seems more proper to me, like: (a-b)@(c-d) (a-b)@c So this is mainly about defining the syntax, more than implementing it. Somebody know more about syntax can comment better. Regards, ferruh
