[Simon Peyton Jones]

Ha!  They didn’t regress for me.  I validated before committing.  How strange.

I agree about keeping it green

These were regressions from your simplifier refactoring. Yes, we should investigate. I'll open a ticket this evening, unless someone else gets to it first. But we surely don't want to keep CI red on every commit until then.

David, are you sure we want to accept a more than 5% increase in compile time without investigation?   What commit caused these increases?  Maybe they are readily squashed? Generally we are trying to improve compiler perf not accept it getting worse!
