Hey Kyle,


In article <dvctqg$269v$1 at digitaldaemon.com>, Kyle Furlong says...

I see what you are saying. I simply replied that it was possible to change the
grammar at this point and that I had a concern about the
validity/usability/maintainability.

I was also pointing out that Ithink that the Do/While/If constructs could and/or
should be symmetric below.

As for the rest...I was just being a little verbose and pointing out that the
grammar is lagging behind the actual parser in this case ;)
