\item[\texttt{e}] The \texttt{e} specifier is in many respects

+ identical to \texttt{x}, but uses \tn{expanded} primitive.
+ Parameter character (usually~|#|) in the argument need not be doubled.
Functions which feature an \texttt{e}-type argument may be

\item[\texttt{f}] The \texttt{f} specifier stands for \emph{full
expansion}, and in contrast to \texttt{x} stops at the first
non-expandable token (reading the argument from left to right) without
