Upgrade GHCJS to 8.6 This allows us to deprecate GHCJS 8.4 (which makes sense, as vanilla GHC < 8.6 is already deprecated). We re-use GHCJS from reflex-platform, which unfortunately isn't up-to-date with latest GHC and is only 8.6. The benefit of using reflex-platform is that it provides nix expressions for GHCJS + a binary nix cache. reflex-platform patches text to use a JS-String based internal representation for performance reasons, so we provide a few haskell dependencies from reflex-platform as well: - hashable - attoparsec As those rely on text's internal representation but have been patched for reflex-platform. 2021-10-09 13:27:01 +02:00			`import (builtins.fetchTarball {`
