ITX suggestion

I know that ITX should be as simple as possible while at the same time giving the design the most flexibility. I am running into one small case that I don't know how to get around. If you want to put something between each iteration of a block, I am not sure I know how to do it unless I hardcode it into the controlling code. Here is an example. I want to end up with link1 | link2 | link3 | link4 from the template <!-- BEGIN LINKS --> {link} <!-- END LINKS --> However, there is no way to determine if I am on the first or last iteration so as to know where to place the seperator. It might be cool if you could set seperator code, such as <!-- BEGIN LINKS { | } --> {link} <!-- END LINKS --> Where everything between the curly braces is the seperator. Since this is an html comment, any html would be allowed without messing up the comment, so you could for instance do <!-- BEGIN LINKS {<br />} --> {link} <!-- END LINKS --> Does this sound good to anyone? The way this would work of course is the very first time the block is parse, it would not be added...then each time after that it is added prior to the addition of the block data. Dan
