Hi, Simon PJ mentions the Core Library committee in this context, but – being a member of that – I must admit that even I were not aware of the changes until they were underway. After I saw the commits coming in I searched for information on the proposal, but only found the ticket #9586 titled “Implement Traversable/Foldable-Burning-Bridges Proposal”, which made me expect some actual proposal somewhere usually in the wiki, but it seems there was none. There is a thread on libraries on Burning Bridges from May 2013, but it was not clear to me that that turned into something concrete. I concluded that I simply missed some discussion somewhere but everything went it’s orderly way. I was uneasy about these changes, but if in doubt I trust those who invest their time. Somewhere in the current thread it was mentioned that it was at the Haskell Implementors Workshop 2013 where this plan was created. I was not there, so that’d explain why I wasn’t aware of the changes at that time. What lessens can we learn from the BBP process? * Personal meetings are great, but please remember to actively communicate results. * Proposal wiki pages, with motivation, examples, alternatives, have served us well. I’m not sure why that was skipped here. We should have them in the future.
