* Packages, Cabal, and GHC --- would like to see: Norman Ramsey, Geoff Washburn
|
|
- 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?)
|
|
|
|
- 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?

- 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:
