---------------------------------------------------+------------------------
 Currently specializing renderers to output various types in a custom
 manner (dropdowns for lists, checkboxes for booleans, etc.) is broken
 because when slots are set to nil, type information is lost.

 We need to modify renderers to accept one more argument 'slot-type', and
 modify 'visit-object-slots' to pass this argument to renderers.

 We also need to add common sense default specializations. Booleans should
 output checkboxes in forms and true/false in data renderers (instead of
 N/A which is done for nils now). Lists (sequences?) should render as
 dropdowns (or local suggest snippets) in forms. We also need to add some
 type aliases. For example 'one-of' types should render as radio buttons.

 How will we render sequences in data renderers? Some options include
 rendering each item in a comma separated list, having a link to datagrid,
 etc.
