This output indicates that the current logical world has seen the

As discussed elsewhere (see defttag), the only reliable way to
validate the ``purity'' of a session is to watch for ``
Another shortcoming of this command is that it only checks the current
logical world for ttag declarations. For example, one could execute a
defttag event; then use progn! and set-raw-mode to

Despite shortcomings, this command might be useful to system hackers. It
also serves to illustrate the inherent flaw in asking a session whether or how
