An unfused map-filter chain is a performance disaster waiting to happen.

  In Go or in general? I've written code for companies with 50k+ concurrent writing users, I've bootstrapped and scaled and sold a startup on Scala (which has bad performance b/c of immutable lists but with usual list <100 elements no problem) and I haven't seen this in other languages, but I'm not experienced enough in Go and haven't deployed something major in Go yet.

    Other popular languages will fuse either via JIT or via some kind of linear types. You should preen less in your comments.

      I think it's always easier to understand a point of view if you know where someone is coming from and the context. "An unfused map-filter chain is a performance disaster waiting to happen." Could you share your experience with that perfromance disaster here?
