    if ($text =~ $LaTeX_parser) {
        $/{LaTeX_file}->explain();
    }

and the chain of C<explain()> calls would cascade down the nodes of the tree,
each one invoking the appropriate C<explain()> method according to the type of
node encountered.

The only problem is that, by default, Regexp::Grammars returns a tree of
plain-old hashes, not LaTeX::Whatever objects. Fortunately, it's easy to
request that the result hashes be automatically blessed into the appropriate
classes, using the C<< <objrule:...> >> and C<< <objtoken:...> >> directives.

These directives are identical to the C<< <rule:...> >> and C<<
<token:...> >> directives (respectively), except that the rule or token
