[rules-dev] removing DSLs

[Wolfgang Laun]

Mark,

in my talk at RulesFest 2011 I've demonstrated that DSLs in their
current form are
indeed useful, perhaps not quite as easy to use as marketing hype
promises.  The current DSL process exploits regular expressions in a
clever way, but this has limits. (Programming in something close to
natural language has been an ongoing
dream since Rear Admiral G. Hopper's fine achievement, but no
remarkable progress has been made in half a century.)

I have presented DSL rules more than once to an audience, and it seems
that getting non-geeks to appreciate rules is made easier this way.

There is nothing in the current DSL that depends on DRL except the
undisputed keywords delimiting a rule. I can see no reason why DSL
shouldn't just stay the way it is: the documentation is fairly complete (much
more than for some other Expert features) and it hasn't needed many
bugfixes I'm aware of.

Cheers
Wolfgang
