Yes :-). I find very strange that the original developers of Axiom did not know this bug (or did not mention it somewhere), after all the construct that triggers this bug is usual. > That phase is improperly putting parenthesis and around things (more > precisely, it misses places where it should put parenthesis). > I suspect a proper fix for that is to do actual tokenization, but the whole > purpose of the preparsing phase is that it is done before tokenization. > A proper fix to that problem is probably: Just Throw Away The Old Parser. Hmm... Do you plan to do that ? That will probably take a while, won't it?
