\section{Meta notations used in this document}
Non-terminals are printed between angle brackets (e.g. $\NT{non-terminal}$) and
terminal symbols are printed in bold font (e.g. $\ETERM{terminal}$). Lexemes
are displayed as non-terminals.
The usual operators on regular expressions:
\begin{center}
\begin{tabular}{l|l}
\hfil notation & \hfil meaning \\
\hline
$\STAR{regexp}$ & repeat $regexp$ 0 or more times \\
$\PLUS{regexp}$ & repeat $regexp$ 1 or more times \\
$\OPT{regexp}$ & $regexp$ is optional \\
$regexp_1~\mid~regexp_2$ & alternative
\end{tabular}
\end{center}
Parenthesis are used to group regexps. Beware to distinguish this operator
$\GR{~}$ from the terminals $\ETERM{( )}$, and $\mid$ from terminal
\TERMbar.
Rules are optionally annotated in the right margin with:
\begin{itemize}
\item a precedence and associativity (L for left, R for right and N for no associativity), indicating how to solve conflicts;
lower levels are tighter;
\item a rule name.
\end{itemize}
In order to solve some conflicts, a non-terminal may be invoked with a
precedence (notation: $\NTL{entry}{prec}$), meaning that rules with higher
precedence do not apply.
\section{Lexical conventions}
Lexical categories are:
\begin{rules}
\DEFNT{ident}
\STARGR{\NT{letter}\mid\CHAR{_}}
\STARGR{\NT{letter}\mid \NT{digit} \mid \CHAR{'} \mid \CHAR{_}}
\SEPDEF

\mid\NT{unicode-letter}
\SEPDEF
\DEFNT{string} \CHAR{"}~\STARGR{\CHAR{""}\mid\NT{unicode-char-but-"}}~\CHAR{"}
\end{rules}
Reserved identifiers for the core syntax are:
\begin{quote}
\KWD{as},

\KWD{match},
\KWD{Prop},
\KWD{return},
\KWD{Set},
\KWD{then},
\KWD{Type},

\end{quote}
Symbols used in the core syntax:
$$ \KWD{(}
~~ \KWD{)}
~~ \KWD{\{}
~~ \KWD{\}}
~~ \KWD{:}
~~ \KWD{,}
~~ \Rightarrow
~~ \rightarrow
~~ \KWD{:=}

Note that \TERM{struct} is not a reserved identifier.
\section{Syntax of terms}
\subsection{Core syntax}
The main entry point of the term grammar is $\NTL{constr}{9}$. When no
conflict can appear, $\NTL{constr}{200}$ is also used as entry point.
