 \subsection{Perl style for, foreach Statements}
 
-\begin{verbatim}
+A Perlish \code{for} or \code{foreach} statement (also known as an iterator)
+should have the folliwng form:
+
+\begin{verbatim}
+foreach my $item (@workingList) {
+    # do stuff with $item
+}
+\end{verbatim}
+
+The current working item should be interacted with through a declared lexical
+variable and  not via \code{$_}.
+
+\begin{verbatim}
+foreach (@workingList) {                # Avoid!
+    # do stuff with $_
+}
 \end{verbatim}
