\section{Enclosures}  There are four types of enclosures: \texttt{(parentheses)}, \texttt{[brackets]}, \texttt{\{braces\}}, and \texttt{"quotation marks"}. \texttt{\"quotation marks\"}.  Each one that you open will need to be closed at some point. This is called ``balancing,'' that is, keeping properly matched pairs of enclosures throughout your code.
