I largely agree with this. HP has done much good for Haskell, but I
feel it's mostly serves as a good starting point for people new to the
language and its community. On platforms lacking good package
management (and here I mean both tools and people) it plays a crucial
role. On a platform like Arch, with good package management and a
stated goal of being nimble and at the edge, it isn't needed as much.

I really appreciate this, since a complete re-build of ArchHaskell's
repo took a couple of days last time I attempted it--and we've added
more even packages since.

It is easy, but time consuming. Just fire any questions on this to
the mailing list, or directly to me, and I'll try to answer as best I

I agree fully. Since I got back to ArchHaskell I've not been very
good with updating packages on AUR. The only packages that have
received updates are the ones that are in our repo too, that means
only about 300 packages get updates, out of roughly 2000 owned by the

Most software today is very much like an Egyptian pyramid with
millions of bricks piled on top of each other, with no structural
integrity, but just done by brute force and thousands of slaves.
