    People complaining about "if err != nil" density in #golang don't check errors in other languages. Discuss.

        @jaqx0r Production code has to handle errors somehow, and the means is coupled to language. #golang style has high cognitive load IME.

        @jaqx0r High cognitive load means less cognition spent on the actual task. Error handling is important; doing so without load is better IMO.

        @rbtcollins you keep saying task at hand and cognitive load like they are different things. Handling failures is part of the task

        @jaqx0r Maybe everyone complaining is just writing bad go code that mixes computation and IO everywhere? I dunno. Interesting angle though.

        @jaqx0r well, exceptions just propagate to the top of the call stack...

        @jaqx0r all software crashes :) so you need something monitoring it...

        @jaqx0r I don't have errors in my types. Therefore there are no errors (c.f. "Why did you put bugs in the code in the first place, Daddy?")

      @rob_pike @jaqx0r In exception-based languages, you often get to aggregate a bunch of similar/same error handling together in one code bit.

      @jaqx0r @sdouche oh yes they do ! \/ or Validation or any possible type . Do 'if(something)' to check nullity, error ... is terrible

      @jaqx0r @rob_pike people that think exceptions aren't necessary can goto fail;

      @jaqx0r @rob_pike problem isnt if err != nil its if err != nil { return nil }. most error handling is propagation. debatable but different

      @jaqx0r prefer encoding possibility of failure into types.

        @jaqx0r They are primarily feeling guilty now that they have to explicitly ignore the errors. Ex: n, _ := r.Read(but). It was hidden before
