This works fine when there is a one-to-one mapping from other-source to Haskell-source file, but there is no good support for other types of preprocessors. For example, for our UUAGC [1] project we also have a cabal plugin [2], and we have the following situation.

This would also be a problem for any Protocol Buffers [1]
preprocessor, where we would typically map one protocol buffer
definition (a .proto file) to several Haskell modules.
