No, I prefer it too.  It would be even nicer with parameterised
modules, so that we could do something like

    main = do
        globalVar <- newIORef 0
        let import (EvenBulkierThanFooAndBar globalVar)
            foo = fff aaa bbb ccc
            bar = ggg xxx yyy zzz
        mmm >> nnn >> ooo

instead of passing globalVar to several of EvenBulkierThanFooAndBar's
exported functions separately.
