GHC 7.0
Summary
The newest major version of the Glasgow Haskell Compiler (ghc) version 7.0.1 was released 16 November 2010. It has many new features, including a new I/O manager, new type-checker, new improved parallel garbage collector, and support for a new LLVM compilation backend.

Benefit to Fedora
Fedora will benefit by providing the latest ghc compiler to its users with many performance and feature enhancements.
Scope
- Minimal impact outside of Haskell packages
- Rebuilding all Haskell packages: see Detailed Description above
How to Test
- Packagers
- Build packages against GHC 7.0
- Many Haskell libraries and applications include test suites already (not many are enabled to my knowledge). Enabling these will help catch errors.
- Testers
- General usage of packaged Haskell applications to find bugs (probably manifest as assertion errors or exceptions)
- darcs
- cabal
- General usage of packaged Haskell applications to find bugs (probably manifest as assertion errors or exceptions)
User Experience
Developers will be able to use GHC 7.0.
Dependencies
- Haskell packages (to be handled by the Haskell SIG for the most part)
- Haskell Platform release (hopefully there will be a release available in time)
Contigency Plan
- In the unlikely event that the version upgrade is not possible, any partial work will simply be left dist-f15-ghc and we will release F15 with the current ghc-6.12.3 set of packages.
