As I've mentioned before [1] I think binary and cereal should be
merged. They are almost identical and both the strict (cereal) and
lazy (binary) runGet interfaces can coexist in the same API,
implemented on top of runGetPartial. The only remaining issue I'm
aware of is that Lennart tried implementing the current binary API
using continuations and it was a bit tricky to maintain performance.

Furthermore, I really think the Put and Get modules should be split,
which implement encoding/decoding of base types in standardized
encodings, should be split from the Binary/Cereal module, which
implement a very specific and non-standardized (but still useful)
format. Not not break any old code I suggest that the binary/cereal
package will re-export this split off API (e.g. a new binary-encodings
