Debugging is simplified by strongly typed languages where Tags are supported and discriminated ...

Also, add some other tag > list based function in foo() to see how having separate tags helps... No programmer can make assumption about the tags OpenURL will additionally accept some day. So he is not allowed to mix custom tags with OpenURL tags. If he wants two sets of tags (a custom one and the one of OpenURL) he has to declare two tag list parameters for 'foo' (then C programmers will get angry, because they can only have one varargs list for every function :-) or he has to provide a custom tag pointing to an OpenURL tag array. ------------------------ Yahoo!
