Are You Using Linear Types in GHC? Um, Yeah. Yeah.

I'm wondering, you've been working on GOC most of the time and GOC itself is, let's say relatively conservatively written. But at the same time you have been implementing all these really cool extensions for Haskell that everybody is keen to use. Do you ever get to use them yourself in anything? Oh, yeah. So we have the, we have this sort of two, two release policy. We try to make sure that JAT can be compiled with itself,. You wouldn't have much luck if you tried to compile GHC now with, uh, you know, GHC 4.2.
