Hi, Is it possible to mix dsl language and regular rule syntax in a rule file? I am trying to do this, but my rules won't compile. The "unable to expand" error is returned during compilation. I tried adding [*][]"{anything}" = "{anything}" to the dsl file to fix this, but that didnt work. I used this strategy in Drools 4.0.7, but it doesn't seem to work in Drools 5.0.0 M5. Below I provided a simple example of what I would like to do.
