Template keys are unsupported at present in DSL. I hope to be able to address in the near future, but unfortunately cannot commit to exactly when.

Thank you Manstis for quick response.

What I suggested is a non-standard way of rule authoring, and I just think that it is possible - I've never tried it.

OK, thanks for the confirmation. Do you have any comments w.r.t. to usability during development (debugging?!) and maintenance? The example is simple enough, but what's your feeling? -W On 6 January 2012 08:46, FrankVhh &lt;frank.vanhoenshoven@&gt; wrote: > > laune wrote > > > > What I suggested is a non-standard way of rule authoring, and I just > think > > that it is possible - I've never tried it. > > > > This should work.

Hi Frank, thanks for your follow-up. As much as I like source code generators, I must confess that I've come to dislike the generation of many almost identical chunks, e.g., varying only in literals. This means that using templates without an "if" in the available macro language is a "weak" tool. Consequently, this triple layering isn't on my "tops" list. Basically, I agree with your assessment, the only caveat being the level of complexity and extend that is convenient to achieve with a DSL.
