Yes, trying to do anything complicated is always very painful in syntax-rules, and every once in a while, you really do want unhygienic macros. Explicit rename is much simpler to understand, and more powerful. The only problem is that it's easier to make a macro unhygienic. But I figure that if you are already programming in a lisp, you can handle not having the language hold your hand through hygiene, it doesn't anywhere else.
