Yes, I was unaware of Smolka's early work and it does look very nice. (Much of Smolka's work seems underappreciated.) The evaluation in the paper under discussion of this work seems weak given that Smolka's early effort has a very similar set of features to what they want.

I concur about the research silo-ing. However in this case we have Europeans ignoring Europeans, and on that CTM page you will find a grab from a review in the Journal of Functional Programming. Several authors of this paper have published in the JFP, leading me to conclude that the JFP is a write-only journal, like much of CS literature.
