[Haskell-beginners] Export two modules from one.hs file?

[Leonhard Applis]

Hey  All,

I currently want to make a module, which "truly" exposes 3 functions. However, there are more functions which I want to test.
I would like to export two modules from the same file, "ModuleToUse" and "ModuleOpen".
Then I can use ModuleToUse everywhere else, and ModuleOpen in the UnitTests.

I know I can declare ModuleOpen, and export only certain functions with ModuleToUse.
But I am not sure, if that is a smart / normal thing to do. In my case this would double my modules, and ... hence files?

What is the "real world" approach for this?

Thanks
Leonhard
