Your average casual programmer. I mostly focus on C#, but I am also learning C++, C, Bash, Perl, Python, HTML, CSS, Javascript, Java... Oh God, that's a lot of languages...

if(MyBool = true) 
    { 
    try { bool YouAreAnnoyedByMyCodingStyle = true; } // And yes, that is how my code looks.
    catch { bool YouAreAnnoyedByMyCodingStyle = false; } // And again, yes, I try-catch like that.
    }
