Nice idea, but this way you still need to modify the single module which glues them alltogether. I wanted to allow the users of the module add some functionality to the module itself. Thanks for the perspective though, -- Ozgur 2009/11/30 Roel van Dijk

Is there a way of splitting the definition of a module into multiple files?

Let's say you have some module A which introduces 3 symbols:

module A (a, b, c) where a = 1 b = 2 c = 3

Now we will split it in 3 modules:

module B ( b ) where b = 2

module C ( c ) where c = 3

module A (a, b, c) where import B ( b ) import C ( c ) a = 1

You can also do the inverse: create a single module of which parts are exported in multiple other modules. This can be useful to avoid circular dependencies while still presenting a nice interface to your library users.
