I know a few teams in Walmart Labs use Clojure, so there's at least some small percentage of the tech side adept in the functional world.

Very cool to see a startup built on .NET and Azure sell for $3B!

Walmart.com is a pretty big user of Scalia already

It makes sense they want to buy Jet, since what they are currently using is dead.

Apparently the replacement has been proposed already, but the powers that be keep shutting that down, too.

Clojure as well, e.g.: http://blog.cognitect.com/blog/2015/6/30/walmart-runs-clojur...

They're pretty language agnostic from what I've heard, not always in a good way.

Could you expand on this a bit? Does that mean that they don't have a common set of internal libraries?

That's a shame, I heard Scalia's been dead for a while.
