Add instances Show1, Eq1, Ord1, NFData, Arbitrary, Series?

[kindaro]

I would like to see some more classes defined for intervals. So far I have had a need of and defined the following:

• Show1
• Eq1
• Ord1
• NFData
• Arbitrary
• Series

It is mostly a triviality to define. I can make a pull request.

Arbitrary and Series incur dependencies that may not be acceptable for the user of the library. Possibly a small companion package can be added to the repository to encompass these.

I’m not keen on adding dependencies in general, but companion packages seem totally reasonable. NFData will require a deepseq dependency IIRC, but I don’t think I mind that one.

I don’t recognize Series; what package defines it?

[kindaro]

Actually it is Serial, my fault.

@robrix  I put forward 2 pull requests, hopefully they are self-explanatory. I propose we move the conversation to the respective pull request tickets #7 and #8.
