Comment (by splinterofchaos):

 Tentatively, I could, although I wan't sure of the best policy.

 Perhaps later today, if I have some time but otherwise tomorrow, I might
 do so. Since GHCi's solution seems to work, I'll just factor it into
 `InteractiveUI` or a submodule, if more appropriate. Although, on second
 thought, it would seem more consistent with the current API if instead of
 predicate functions, I wrote one returning an ADT constructed with
 something like `AStmt`, `AnImport`, or `ADecl`.
