I think the point about similar languages is important. After using a Java-like language where == can compare Strings, chances are you will use == instead of .equals() when working in Java. Also, when switching between languages like JS, Ruby,and C#, I can't automatically type semicolons and the process involves a quick delay when I have to think about whether there should be a semicolon or not.
