+* Add `+` and `-` to the set of layout-based list syntax bullets.
+  All elements of the list are checked to see that a consistent
+  bullet is used. Different bullets might be used to help make
+  nested lists more understandable. `-` might be used to make things
+  look more like YAML

 * Allow underscores in number literals

+Layout list entries are started with a leading @*@, @+@, or @-@. Each leading bullet
+must occur in the some column of the file. Lists can be nested by starting the new
+list on a column to the right of the current list. A single list must use the same
+bullet token for every element of the list. Nested lists can choose a different
+bullet. This can help visually distinguish nested lists.
 
 Layout based lists can not occur inside inline list syntax. Layout based section lists
 can occur inside layout based lists
