Allison Randal, Damian Conway: Synopsis 5. "Just as you can have anonymous subs and named subs you can have anonymous regexes and named regexes:"
rule ident { [<alpha>|_] \w* }
# and later...
@ids = grep /<ident>/, @strings;
# and then refer to named regexes, such as:
rule serial_number { <[A-Z]> \d<8> }
rule type { alpha | beta | production | deprecated | legacy } Neat and slightly shocking (for someone who's been doing Perl for eight years) syntax.
