 \item [$\isarkeyword{print_locales}$] prints the names of all locales of the

+\item [$intro_locales$ and $unfold_locales$] repeatedly expand

+  $intro_locales$ only applies the $loc.intro$ introduction rules and

+  aggressive and applies $loc_axioms.intro$ as well.  Both methods are

+  target and $\isarkeyword{includes}$ statements, and from
+  interpretations (see below).  New goals that are entailed by the
