Modules and their explicit export lists (are an annoyance)

[Albert Y. C. Lai]

I write an export list because I want to help Haddock. It suffices to 
export a constructor with (..) for this, if I intend to.

How much to export is always politics, bargaining, negotiation, social 
dynamics. There will always be someone annoyed. Exporting too much 
reduces annoyance now by re-paying for annoyance plus interest in future 
when an exported item will be withdrawn or visibly changed.

Discuss with the authors if you believe that more should be exported.
