Hi Jesse,
> Why did ghc-random and ghc-regex-compat only work with ghc 8.4.3?
RIght now, most - if not all - ghc packages are built with ghc@8.4.3. GHC
will check the version it was compiled with and refuse to compile if there
is a mismatch between the object file and your project.
Now that I say that, I am not sure I am right. I get version mismatches
compiling xmonad, for instance, when i upgrade ghc to 8.6.
It would be really nice to get more packages up to 8.6. One solution might
be to use a channel with package definitions using your preferred version
of ghc.
One other problem I can think of is that the current ghc is 8.6 but most
ghc-* packages are built with 8.4 so most packages are incompatible with
the default.
