|Heirloom would go that way). For S-roff i can say that yes, i'm open and want such an extension, but i will not tear up the parsers that yet exist in order to do so. I'm not yet sure but i think introducing the $ extension trigger seems to be a way to get this going, introducing some "outer state" which can be recalled once the existing parser(s) are done. Maybe $ should be turned into a two-letter mode first, however, say $( to mean "grouping", $r "regular expression", $c the already implemented string-case thing. That would be even better (though even uglier). --steffen
