[generics] go2go snippets -- repository of example solutions to problems using generics

[K. Alex Mills]

For my part, I see some value in maintaining a source of example solutions to problems that generics could solve. Since I was not aware of any resource that attempts to gather together several example implementations in one place (and couldn't find one after a couple minutes of searching), I decided to create one.

You can find it on GitHub at go2go-snippets.

For the moment, it's mostly incomplete, but even so, there's no reason not to share it. I am hoping that the community might help to fill in some of the gaps before I get to them. I also want to encourage submitting multiple implementations for the same problem. Having a variety of solutions to look at and compare can help the community learn about idioms that may and may not be useful, and could yield some productive insights.

Feel free to also submit any generic code you've tinkered with; along with a statement of what concrete problem it aims to solve.

I hope that having a set of concrete implementations to refer to helps to clarify at least part of the impact of the current proposal both for the designers and the community.

One final point deserves some mention. As the prototype evolves, some of these examples may go out-of-date, and they may or may not be maintained. I'm fine with that. None of the examples should be large enough on their own that this will represent a significant loss of effort. In my view, the benefit we would gain from even a transient set of examples will outweigh any time invested in their creation.
