I'd take the abstraction over compile times, but not having near-instant feedback is a huge compromise. But I've never known it to miss it.

Is it first compile only that's slow, or all subsequent compilation? What times are we talking, roughly?

I'm not using Scala, so I have no insight into this, but it's interesting nonetheless.

Hard to give meaningful figures, but a "small" project can take 2-3 seconds to compile; a 1000 person-year project, maybe 30-60 mins.

Yeah, of course. I can see how that's a problem. :/ I recall something about Go compiling its standard lib in ~1s.
