> it was a problem with IntelliJ in several of our code bases
It shouldn't be, unless you were using macros (always officially experimental) or something - I was always primarily an Eclipse guy but IntelliJ worked well. Did you not get the green underline?
We weren't using macros, but one of our major dependencies was (geotrellis).
Didn't seem to matter how close to geotrellis we were though. That being said, I'm willing to buy that it confused IntelliJ enough that it gave up on entire packages
Either way, we ported a couple of the abstractions from there to go and just used that. The build times plus getting away from sbt have been enough of a win to keep us on go, and that's before we get to the memory reduction on in-memory rasters
I eventually opted to desugaring the scala completely, but we were already on the way out of scala by that point
