Encourage improvement after submission

[dpashkevich]

The README for the beer song exercise has an important section that reminds people of the end purpose of all the exercises:

## For bonus points

Did you get the tests passing and the code clean? If you want to, these are some additional things you could try:

* Remove as much duplication as you possibly can.
* Optimize for readability, even if it means introducing duplication.
* If you've removed all the duplication, do you have a lot of conditionals? Try replacing the conditionals with polymorphism, if it applies in this language. How readable is it?

Then please share your thoughts in a comment on the submission. Did this experiment make the code better? Worse? Did you learn anything from it?

Why not print it in the CLI tool after the user submits his next exercise?

I like this idea. I'd like to see a whole bunch of different variations on it so that people don't automatically ignore it.

[dpashkevich]

Well maybe we can just rotate a set of predefined phrases for the first implementation.

[kytrinyx]

That sounds good to me.

Is anyone still interested in this issue? I was directed here from 24pullrequests and this sounds like a good place to start out.

[kytrinyx]

Yeah, definitely still interested in this one. Up for grabs if you want it.

[eToThePiIPower]

Great. I've got a preliminary version done. For the moment I thought it'd be best to only show it on the first iteration for each exercise (to keep down the annoyance factor), and hard-wrapped the lines to 80 characters.

Still working on a rotation/randomization scheme to keep some variety as you suggested. I think randomization will be easier to implement without having to keep track of the state somewhere.

[kytrinyx]

Yeah, I think you're right -- we don't need to show it on subsequent iterations.

[eToThePiIPower]

So I've got a simple random rotation going on the "header" to provide some variety (per your suggestion for adding variety). Currently:

• For bonus points
• Don't stop now: The fun's just begun
• Some tips to continue

It should be easy to add more (suggestions for creative phrases would be appreciated)

With enough of a selection of creative header phrases, I feel this would be enough variation. Randomizing the whole tips probably wouldn't be worth the extra complexity, at least at this point.

[kytrinyx]

Agreed--let's start with this and see how it feels in action.
