It may be just me being confused, but the symbol that looks like a U (U+222a) is usually union; intersection is the vertical reflection of that (U+2229). I'm not trying to be picky, but if it's confused me, it's probably confused someone else too. All of which reminds me, I'm looking forward to being able to iterate over my lists with \forall, \elem, and other set notation symbols rather than having to spell stuff out. Perl up to 5 may be executable line noise, but I can see Perl 6 being the closest thing yet to executable maths, and I love it. -- Always crash crash crash Well come on and let me know You're happy when I'm running bash Should I play or should I code?
