# Abstract
This TIP proposes to change the name of the introspection subcommand
of the _trace_ command from _list_ to _info_.
# Rationale
Although the functionality of the _trace_ command \(as extended by
[[62]](62.md)\) is good, the name of the introspection subcommand, _list_ is
not such a good choice:
* The name _info_ is already well known for introspection purposes
in Tcl \(e.g. [info] and [after info].\)
* The name [trace list] could be misunderstood as having to do with
tracing lists.
* The introspection subcommand to trace could be extended to allow
more specific queries along the lines of [info commands], [info
procs], and [info vars]. _\(This is outside the scope of this
TIP.\)_
Hence, this TIP calls for the _list_ subcommand to be renamed to
_info_. \(Note that this also makes the subcommand for introspecting
on variable traces more similar to its old form _vinfo_.\)
