You mean foo '-'1 is parsed as (-) foo 1 and foo -1 is parsed as foo (-1) right? Yes! It was my mistake...

What would foo - 1 mean? If it means (-) foo 1 then putting the extra space in looks a lot nicer to me than using backquotes. If it means foo (-1) then I think this will break a lot of code, and is also very unintuitive. As for me, it must still parse as foo (-1). While this solution _is_ contra-intuitive, any other variant is _worse_. I suppose, parsing can take differently 0 and 1 spaces, but not 1 and 2...
