I was assuming from Larry's mail that <[a...]> would parse as either: 1) a character class containing the range from 'a' to '.' (what that means is a bit mind-bending for a friday afternoon) 2) a character class containing 'a' then a range from '.' to... oh, an error Which way might be ambiguous, but could of course be defined in the grammar. It hadn't occurred to me that ... for the range to infinity would be allowed or useful here. I suppose it could just mean 'up to the end of the available codepoints'. I do love the idea of <[a..f]> type ranges though. It's just what the three dots mean that's got me confused.
