> I have secret knowledge, why don't you spend T amount of your time on some big project to maybe come to the same secret insights I mean Alternate interpretation, I learned something valuable from doing this thing, perhaps you'd be interested in doing so as well since the book that took months or years to write will do a better job teaching it than I will in a five minute break while typing on HN. It's always impressive when freely sharing knowledge and tips is somehow taken as being insular and exclusive. > If you have an opinion on why pattern matching is so complex and undesirable Where did I say pattern matching is undesirable? It sounds more like you just want a fight here. Remember the HN guidelines: > Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

> It's always impressive when freely sharing knowledge and tips is somehow taken as being insular and exclusive. But you didn't share knowledge. You suggested that you had knowledge that was pertinent to the topic at hand. But you didn't share it. You did share tips for resources where one can learn more, and that's great. But you didn't add something like "... and that's where I learned that pattern matching is undesirable because <technical reason>". > Where did I say pattern matching is undesirable? This whole thread was about you saying that pattern matching was undesirable from the point of view of Go's designers or implementors due to their design goal of simplicity. Then you mentioned those compiler resources. The only reasonable interperetation for me is that you wanted to say that you did indeed know concrete technical reasons why pattern matching in Go would be complicated and therefore undesirable.

  > This whole thread was about you saying that pattern matching was undesirable from the point of view of Go's designers or implementors due to their design goal of simplicity. The only use of "undesirable" in any of my comments was in regard to features that are prevalent across languages today. If you must know I was thinking of inheritance and exceptions specifically. As far as pattern matching goes, I was making no arguments except to say that I like it, adding a feature like pattern matching adds some non-zero amount of complexity, and that the go authors are apparently uncomfortable with that complexity. As I am not a go author, I am unsure of their exact reasoning and would not think to say why they believe that. My implication was not that I have an exact concrete reason for why the go authors feel the way they do. It was merely that I don't inherently disbelieve them when they say they have a reason. In fact my exact wording was "I think that's a perfectly reasonable stance to take", which does not imply agreement, only a lack of strong disagreement. In other words I don't think they're ignorant of the matter or misrepresenting the situation. > But you didn't share knowledge.

But you didn't add something like "... and that's where I learned that pattern matching is undesirable because <technical reason>". The comment that appears to have gotten you riled up was after the person I was talking to saying they understood. After a discussion about language complexity I thought that it would be appropriate to suggest some resources on a "quick" project that can help build an intuition on that topic. And to be honest, it's a project I like to find excuses to suggest. I find people tend to be surprised at how easy and fun it can be to make some meaningful progress. I understand that you would like for me to somehow short circuit that process, but I don't believe I am capable of building someone else's intuition by posting a throwaway comment on HN. Intuitions are typically built on experience and tinkering, not reading someone else's experiences. That you view that project suggestion as a continued argument is unfortunate, I can assure you that was not my intent. Again referencing the HN guidelines, I encourage you in future to try to read people's posts first with the assumption that they are being genuine and only fall back to an assumption of malice when you absolutely have to. Long drawn out arguments over semantics don't help anyone.
