trace the indicated functions after creating an active trust tag
Major Section:  TRACE

(trace! (fact :native t :entry *foo*))

General Form: (trace! spec1 ... specn)

where the fni are suitable arguments to trace$.

Trace! is a version of trace$ that avoids the need for an already-active trust tag (or ``ttag''; see defttag), as explained below. See trace$ for when a trust tag can be necessary.

See untrace$ for how to undo the effect of trace!.

The evaluation of a trace! form causes temporary creation of an active trust tag, :trace!, followed by the corresponding trace$ form. The trust tag will disappear when the call to trace! completes. Even though trace! will remove its temporary ttag, it will still print a ``TTAG NOTE'', which indicates that the session is suspect. See defttag and see ttags-seen for further remarks on this issue.
