Inspired by #248, I propose we add tests that demonstrate that the IsExprBuilder methods of ExprBuilder preserve abstract values. One option would be to randomly generate expressions over a single base type (e.g., trees of string operations), then interpret them directly in the abstract domain and also via ExprBuilder methods, and assert that the abstract value of the latter refines the former.
