I think of "unless" as an alternate spelling for "if not", so it seems natural that it be possible to follow it with an "else". I'll grant that the (common) idiomatic usage of "unless" doesn't include an "else", but that seems more an argument not to use an "else" rather than to forbid it. It's a bit like saying one can "continue" after a "while" but not an "until". Is there a parsing advantage that I've missed, or does it disambiguate some other construct? -- Regards, Charles Bailey Lists: bailey _dot_ charles _at_ gmail _dot_ com Other: bailey _at_ newman _dot_ upenn _dot_ edu
