Yesterday, @mikegai had a very fruitful discussion with me about significantly enhancing the performance characteristics of Precept for certain operations without compromising its declarative language. This is intended to be...
When we have attributes that share the same namespace, e.g.: ``` :explanation/rule :explanation/bindings :explanation/facts :explanation/matches ``` it would be handy to match on "explanation". We do not currently allow this....
