Carl even sent me a mail saying it IS in the plans... but he sent me
that just about one year ago!
I have been implementing my own document language. The main difference
is that it is a natural language and the lack of this parsing feature is
making my work Extremely complicated.
That is because I do not want to impose strict format structure... so I
do not know if the document writer is going to end his line right away
or if he wishes to continue on the same line or if he'll put a space or
two, or put a space just before the end of the line...
Add to this the fact that the keywords themselves are plain english (or
any other language, in fact :-) and ARE allowed within the content
itself and it makes the parsing a little bit harder still!
This parsing feature alone would have cut my development time in half at
But alas nothing is perfect, life WOULD be dull indeed! ;-)
Note to RT: Just one tag (like any, to, some, etc) called "next" would
be easy to include in parsing engine no?
