: - PGE doesn't implement <ww> by default, because that's not (yet?) : part of the spec. It only appears in PCT::Grammar, for people : using the Parrot Compiler Toolkit to create languages.
I have wanted <!ww> a number of times, particularly after generic tokens that might or might end in \w. So feel free to spec it. : - AFAICT, apostrophe and hyphen are not yet "word characters" in : the sense of being members of \w . That is, they're considered : to be valid in identifiers, but only when they are immediately : preceded by a word character and immediately followed by an : alphabetic character. Otherwise they're not part of the : identifier. (At least, that's how the current STD.pm reads.) That's correct, we can ignore ' and - for that purpose. Larry
