Okay, I checked, and I'm not sure how you propose to handle curly-infix. It seems, according to your examples, that a line composed of a single curly-infix item is that item, not a list of that item.
In fact, I think I want to be very clear on what, exactly, it is that you envision the following code to be in s-expressions: define : fibup maxnum count n-1 n-2 if {maxnum = count} {n-1 + n-2} fibup maxnum {count + 1} {n-1 + n-2} n-1 >From this example, it appears that there's special handling for curly-infix, because using the set of rules I derived from what I think is the intent of your ruleset (and hand-processing ":"), this becomes: (define (fibup maxnum count n-1 n-2) (if (= maxnum count) ((+ n-1 n-2)) ; huh?? (fibup maxnum (+ count 1) (+ n-1 n-2) n-1))) In fact, I think I want to be much more clear here: So: can you be more clear about how your indentation-based syntax interacts with the n-expression stack?
