Of the 372 direct reverse dependencies of haskell98:

http://bifunctor.homelinux.net/~roel/cgi-bin/hackage-scripts/revdeps/haskell...

there are 344 which also depend on base (See http://hpaste.org/47933 for calculating the intersection).

Is it easy to check, out of those 344, how many would build if the dependency on haskell98 were removed? I suspect it's not needed for the majority of cases.

+1 for Plan A, but interested in mitigating the negative consequences.

This thread seems to focus way too much on Hackage alone. What about all the existing codebases out there, in production? -- Lars Viklund | zao@acc.umu.se
