Okay, another crazy idea: period only has an indentation meaning ONLY if it's followed by tab or space. Pros: * Don't need to escape symbols beginning with "." (unless it's "." itself, which is a highly improbable first symbol on a line for a list). * You can still use period to "draw" indentation levels in very long definitions or sub-clauses (which I admit is useful - and clever). * No special "column 1" rule Cons: * Now period *HAS* to be followed by space/tab if it's to have its indentation meaning. If you use 2+ space indenting that's no big deal, if you use 1-space indenting that's annoying. Under this semantic, the previous example still works: > define-syntax do-it > . syntax-rules () > . group > . do-it > . x > . group x > . group > . do-it > . x > . body > . ... > . group begin > . x > . do-it > . body > . ... --- David A.
