Type provider in Scala

Hi everybody! In 2013-2014 i heard about plans implementing type provider in Scala. What is progress of this project? It’s abandoned or in development stage?
I think, it’s very actual feature, because Scala become more popular in ML, statistics domains.
Ammonite script + some ML lib + some library which can give access to DB with type provider + plot library, сan play a decisive role in productivity.
