\section{Module Organization}

In this section the syntax of EOL is presented in a top-down manner. As displayed in Figure \ref{fig:EOL.Module}, EOL programs are organized in \emph{modules}. Modules can import other modules using \emph{import} statements and access their operations, as shown in Listing~\ref{lst:ExampleImports}.

Each module may define a 
\begin{enumerate}
  \item number of \emph{import} statements
  \item block of EOL statements to execute
  \item and a number of \emph{operations}.
\end{enumerate}
The body is a block of statements that are evaluated when the module is executed. Each operation defines the kind of objects on which it is applicable (\emph{context}), a \emph{name}, a set of \emph{parameters} and optionally a \emph{return type}. The body ends when the first operation definition is encountered and thus statements outside an operation will be silently ignored after the first operation definition.
