And the enhanced package system is implemented in each compiler? Or
just once in the infrastructure, perhaps by a script? Or a mixture of
One difficulty is that if the infrastructure requires certain extensions
to the package system, then we can't start using it until new compilers
come out that have the required extensions.
There are some aspects of the infrastructure that I really don't want to
provide in GHC as part of its package system: the details of building
libraries several ways, installing them in the right place, building and
installing documentation, etc. etc. So I think this stuff belongs in
the infrastructure one way or another.
However, I'm not proposing to implement this stuff (I'm hoping someone
else will volunteer ;-) so whoever does the job gets to choose the
implementation strategy. Obviously we'll help out with any extensions
to GHC that are needed.
