(Not the &amp;quot;out int x&amp;quot; change, but the whole idea of &amp;quot;out&amp;quot; in an argument list to begin with to indicate values coming &lt;i&gt;out&lt;/i&gt; via &lt;i&gt;the arguments&lt;/i&gt;.)&lt;p&gt;The path out of mutable argument bug-hell is &lt;i&gt;not&lt;/i&gt; to declare that the values of some argument variables &lt;i&gt;will intentionally&lt;/i&gt; get changed by the function in the scope where it is called. It is to make arguments immutable (like they are in the traditional mathy definition of &amp;quot;function&amp;quot;), &lt;i&gt;period,&lt;/i&gt; and allow multiple assignment to the function call. What I mean is that, conceptually, ideally, values and state should &lt;i&gt;only flow into the function arguments&lt;/i&gt; and &lt;i&gt;only back out of the function call itself.&lt;/i&gt;&lt;p&gt;So for example instead of&lt;p&gt;&amp;gt; p.GetCoordinates(out int x, out int y);&lt;p&gt;I think the following would lead to reduced cognitive load and thus fewer bugs:&lt;p&gt;&amp;gt; int x, int y = p.GetCoordinates;&lt;p&gt;or even better (color me biased by Erlang&amp;#x2F;Elixir):&lt;p&gt;&amp;gt; {x, y} = p.GetCoordinates; # as a pattern match&lt;p&gt;Instead of a smoothly mentally-traceable flow of values into function arguments and out of function returns, we have this monstrosity of conflating mutable arguments (where values go in &lt;i&gt;and then come back out changed in the scope of the function call&lt;/i&gt;) with this &amp;quot;out int x&amp;quot; business which seems to be indicating it intends to &amp;quot;push values upstream&amp;quot;, as it were.</text><parent_chain><item><author>ZeroClickOk</author><text>What I love in C# is, each update the language gets even faster, far more natural to write.

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>jfroma</author><text>I worked for 6 years on C#, I was C# MVP and I really enjoyed the language.&lt;p&gt;4 years ago I started to work more with js and then node.js until I stopped working on c#. Js has been for me a gateway to transition to other languages and get paid for that. I learned bash, python, a bit of ruby, go, etc.&lt;p&gt;If I see c# code today I don&amp;#x27;t understand what it does. Sure every version has a lot of new very useful stuff but it also introduces noise, &amp;quot;why he used out x instead of the new shiny out var x, he might not know about it, lets send PR&amp;quot;.&lt;p&gt;Along the way I have learned to appreciate simpler languages that does not change that often. Where there are few or just one way to do something.&lt;p&gt;I think I read an interview to Mitchel Hashimoto (hashicorp) and he said he choose Go over all languages because it was boring.&lt;p&gt;A boring and simple language allows you to focus on the problem you are solving. A language that doesn&amp;#x27;t change for years allows people to catch up and master the tool. It also means that you can open a file written by someone else years ago and understand what it does.&lt;p&gt;IMHO js was in that sweet spot until ES6.</text><parent_chain><item><author>ZeroClickOk</author><text>What I love in C# is, each update the language gets even faster, far more natural to write.
