This is excellent news -- thank you Read!
Since FEA is basically a simple programming language, this really is "functional programming". In some cases, it makes sense to put all your detail definitions in a separate block, or a header, or an include file, and use them freely inside your implementation without having to worry about the details. Of course, in many project, the way it currently works is fine, but is some more complicated stuff, separating the lookups from the features would be useful.
It would also be very useful when porting OTL code between VOLT, FDK and other technologies: VOLT stores lookups and features separately, which is useful in more complicated projects.
