## Suggestions from the floor
|
|
* How Template Haskell is implemented
|
|
|
|
|
|
- It would be quite interesting to hear what parts of GHC are changing rapidly and what parts seem quite stable. Also, into which corners of the compiler do the righteous fear to tread? (The evil mangler?)
|
|
* Packages, Cabal, and GHC --- would like to see: Norman Ramsey, Geoff Washburn
|
|
- It is unclear how binding group analysis influences the use of 1 abstract syntax (HsSyn): how is the required ordering and grouping implemented, how does it affect error messages?
|
|
|
|
- How does this Cabal thing work?
|
|
* Past or present efforts in formal verification of GHC components
|
|
- How to read a dailysnapshot build log.
|
|
|
|
- Does ghc compile with VisualHaskell yet?
|
|
* Details of the GHC-as-a-library API, and how to use it. -- Norman Ramsey, Andy Gill, Geoff Washburn, Jeffery Zhang
|
|
- In the compiler pipeline, please explain a little more about the invariants as a program flows through the pipeline. For example, toward the back end, it would be useful to know at what point the following become known:
|
|
[[BR]]

- layout of heap objects
|
|
|
|
- explicit heap pointer (allocation pointer)
|
|
