Use :add instead of :load for Geometry.Cube. :load loads the specified module but forgets anything that was previously loaded. :add loads a module without forgetting previously loaded things.
The differeces between :load, :add, and :module/import are somewhat subtle and certainly confusing. You may find

Thank you for the suggestion. I will read up on scope and try using add. But what I would really prefer is to be able to import individual submodules in GHCi using standard import syntax from the GHCi command line: Prelude> import qualified Geometry.Sphere as Sphere Is that not possible? LYAHFFG seems to imply that it is, and Daniel’s response to this question seems to also suggest that it’s possible. Then I can control how the functions in the submodule are referenced. Thanks again, James
