      \fitem{\&\&}(\vValue, \vValue), \vListable: functional form of the
      infix \code{\&\&} logical conjunction. Contrary to the operator,
      the functional form is \emph{not lazy},
      cf. sect.~\ref{sec:lazy_logical_operator}
      p.~\pageref{sec:lazy_logical_operator}: so \code{@&&(a, b)}
      evaluates \code{b} irrespectively of the value of \code{a}
