It is a fair point-- the implicit argument being that this allows `c` and `d` to be bound before they are used, and hence auto-complete can assist in the `select` clause. Nevertheless, the counter argument is that the form of a logic rule is:

  Path(x, z) :- Path(x, y), Edge(y, z).

i.e. an implication from right to left. This structure matches:

  query p select (x, z) from Path(x, y), Edge(y, z).

So the trilemma is:

A. Keep the logic rules and `query` construct consistent (i.e. read from right-to-left).

B. Reverse the logic rules and query construct-- thus breaking with decades of tradition established by Datalog and Prolog.

C. Keep the logic rules from right-to-left, but reverse the order of `query` making it from left-to-right.

We decided on (A), but maybe we should revisit at some point.
