No. Do we know which packages would break? I imagine that downloading the hackage tarball and grepping for 'instance Bits' should tell you.

Where can this tarball be downloaded?

http://hackage.haskell.org/packages/hackage.html "archive of just the latest versions of all the packages (230MB tar file)"

Also, does this have any performance impact?

Performance should not be affected. After inlining all instances should use the same definitions.

Good. So none of the current instances use the default* functions? -- Johan
