Getting a goals list

Roadmaps are hard and take work. The goal here is to distribute the work a bit. The plan is:

1. Get a list of statements from each of the core maintainers as to what their roadmap plan is
2. Use that information to make a first draft of a roadmap
3. Open a PR so that people can make final edits and changes
4. Have it on the website so then it can be updated yearly / every few years.

Steps 3 and 4 are not as much work, so I believe the issue is just the inertia of getting there. I can help get there, but I'll need the following information.

From each of the core maintainers for Julialang and the standard library, can you share your:

* one year plans (short term goals)
* 3 year plan (medium term plans)
* 5 year plan (speculative long term ideas)

**This can be a simple one line sentence**, or it can be a whole paragraph story. Mostly this is to get a list of all things that need to enter the final story.

I got "unofficial" permission from @mbauman to ping everyone, so hopefully this isn't bad. Here goes nothing:

And please anyone I missed that should be considered in this list of "people likely to make major contributions in the near future".
