=head1 SYNOPSIS
=back
-=head2 C<TOPLEVEL>
+=head2 C<unwind @values, $level>
+
+Returns C<@values> I<from> the context indicated by C<$level>, i.e. from the subroutine, eval or format just above C<$level>.
+The upper level isn't coerced onto C<@values>, which is hence always evaluated in list context.
+
+=head1 WORDS
+
+=head2 C<TOP>
Returns the level that currently represents the highest scope.
+=head2 C<HERE>
+
+The current level - i.e. C<0>.
+
+=head2 C<UP $from>
+
+The level of the scope just above C<$from>.
+
+=head2 C<DOWN $from>
+
+The level of the scope just below C<$from>.
+
+=head2 C<SUB $from>
+
+The level of the closest subroutine context above C<$from>.
+
+=head2 C<EVAL $from>
+
+The level of the closest eval context above C<$from>.
+
+If C<$from> is omitted in any of those functions, the current level is used as the reference level.
+
+=head2 C<CALLER $stack>
+
+The level corresponding to the stack referenced by C<caller $stack>.
