I'm going to keep mucking about with sdl, following some tutorials. I'll see if anything else pops up and send a PR.

Maybe related to #3217 that was just recently merged? Looks like the problem is that the whitespace before/after each ns in the list isn't propertized correctly, so in cider-browse-ns--thing-at-point, ns-p...

@weavejester just made #337 as a quick poc, I have no idea if it's even correct, but something like that as the basic idea?

@weavejester I updated the poc, I think it's at a state where it might be worthy of an initial code review, although it's still a little rough maybe
