Treatment of spaces, such as the trap that \verb|\~~a| is equivalent to \verb|\~a| in expl syntax, or that \verb|~| fails to give a space at the beginning of a line. \section{Structure of tokens} Copy there the section ``Description of all possible tokens'' from \texttt{l3token}. \section{Quantities and expressions} Integer denotations, dimensions, glue (including \texttt{fill} and \texttt{true pt} and the like). Syntax of integer expressions (including the trap that \verb|-(1+2)| is invalid). \section{\LaTeX3 terms} Terms like ``intexpr'' or ``seq var'' used in syntax blocks. \end{document}
