It lets you make additional pattern variables you can use in the template".  Do you think that would be helpful, or, misleading?

A little light bulb went off, i.e. wow, that name would have helped me grok the concept faster. To be clear I'm not critizing `with-syntax' or `define/with-syntax' being chosen.

However, I cant figure out how to make it give me the output in a list and address each element of the output.

19:56 didi: Kyndar: It's the same page.
19:56 Kyndar: more like this, but with adding 1 to the output every time and then the final a value as the second element in the output
19:56 Kyndar: oops http://codepad.org/vTamPXMT
19:57 didi: Kyndar: See, you're not using (- a b).
19:57 Kyndar: i see, so i will use (div (- a b))
19:58 didi: Kyndar: That's a step closer to the solution.
20:01 Kyndar: http://codepad.org/ciIcq5nn now it gives the remainder, but how do i have it give me the number of times it repeated
20:03 didi: Kyndar: You might have to keep the counting using another parameter.
20:04 Kyndar: i dont quite understand. In any other language i would set a new variable and add 1 to it each time it recurses, but i do not know how to do this in scheme
20:05 didi: Kyndar: Sure you do!
