Are the following correct?
1. Hat requires users to restrict themselves to a certain small subset of the standard libraries, and to use hmake
Depends what you mean by standard libraries. As far as I know it supports all the libraries which are specified in the Haskell 98 Report. I believe it also supports some libraries in the new hierarchy that come with the compilers. Also, many libraries can be used by Hat, if you include them in your own source tree. Supporting all libraries that come packed with GHC would be nice, but there are numerous hurdles that need to be jumped over to get to that point. For instance, some libraries do not use portable Haskell code. Also the issue of how libraries are distributed in Haskell is a little bit in flux at the moment, since Cabal is still being polished.
This doesn't really have anything to do with Cabal as far as I know. Hat comes with pre-translated libraries for a subset of the GHC libraries. It's true that the libraries that come with the compilers may change in the future, partly due to Cabal, but I don't think this is the reason that Hat doesn't come with all the libraries. Hat doesn't even use Cabal, AFAIK, but hmake.
2. Buddha doesn't work with GHC 6.4
True. This is a cabal issue, that I haven't had time to resolve. buddha is limited to even fewer libraries than Hat.
Why is this a Cabal issue? Are you interested in adding Buddah support to Cabal? peace, isaac
