Hi, I'm looking at the packages blaze-builder and bytestring, and both provide builders for ByteString. Which one should I use? In which situations is one more convenient than the other?

I'd say the usual answer here would be bytestring. Both implementations are by Simon Meier, but the bytestring one is the later one with various refinements and more API review. The bytestring one is intended to replace the blaze-builder one. The bytestring one is in the platform. The blaze-builder one still has some extra special-case functionality such as for html encoding. I *think* (but not 100% sure) that Simon's plan is to make blaze-builder re-export the bytestring builder and just add the few extra functions on top. Duncan (bytestring co-maintainer)
