This TIP proposes to change the name of the introspection subcommand of the \textit{trace} command from \textit{list} to \textit{info}.
\end{tipabstract}
\tableofcontents\setcounter{page}{0}\clearpage\pagestyle{plain}

\section{Rationale}

Although the functionality of the \textit{trace} command (as extended by \cite{tip62}) is good, the name of the introspection subcommand, \textit{list} is not such a good choice:
\begin{itemize}
\item{}
The name \textit{info} is already well known for introspection purposes in Tcl (e.g. [info] and [after info].)
\item{}
The name [trace list] could be misunderstood as having to do with tracing lists.
\item{}
The introspection subcommand to trace could be extended to allow more specific queries along the lines of [info commands], [info procs], and [info vars]. \textit{(This is outside the scope of this TIP.)}
\end{itemize}

Hence, this TIP calls for the \textit{list} subcommand to be renamed to \textit{info}. (Note that this also makes the subcommand for introspecting on variable traces more similar to its old form \textit{vinfo}.)
