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)"

Nice, I will take a look.

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?

No, all of them do. But since they previously used the default implementation, which is the same as the default function, the performance should be the same. Bas
