Remove also a few lines of old commented cruft.
Initially I wanted to complete chris' audit of scheme files, but I had quite some difficulties determining whether a given variable is #f or '() if it is to be considered non-existent. I understand that it is easy and reasonable to wrap a NULL pointer as '(), so that it can be tested with null?. But OHOH in a pure scheme context #f is nice too, as it is the only thing with a false truth value. Is there a way to easily see whether something missing, maybe passed 15 scheme frames down the stack) is #f or '()? Or can we mix them without writing (and obj (not (null? obj))), or (or (not obj) (null? obj)) all the time? I do not touch those scheme files very often, so if you think this is trivia, I will not argue about that. -- andi5 _______________________________________________ gnucash-devel mailing list gnucash-devel@gnucash.org https://lists.gnucash.org/mailman/listinfo/gnucash-devel
