I went through the code one more time. It is awesome how the initial 
idea has changed. Now, it really is a big deal—thanks for your 
inspiration on where to apply this transformation.
As I see it, it helps to avoid the linear growth of execution time for 
BitmapOr paths. Also, it opens up room for further improvements related 
to OR-clauses alternative groupings and (maybe it is an enterprise-grade 
feature) removing duplicated constants from the array.
