What you&amp;#x27;ve presented is very much like saying &amp;quot;I don&amp;#x27;t encounter many people with your style of programming and thus, no one uses that style and you&amp;#x27;re not an actual programmer in this language&amp;quot;.&lt;p&gt;Don&amp;#x27;t forget that there are varying styles of doing things. You use &amp;#x27;p&amp;#x27;? great! Others will use foo, i, j, lalal, etc. No need to get worked up over such a minor issue and detract from the actual conversation at hand.</text><parent_chain><item><author>mattmanser</author><text>I hate to be nit-picky, what you&amp;#x27;re presenting is non-idiomatic C#, I would guess you&amp;#x27;re not a C# programmer.
