Please add a comment for content meaning and possible values.

BTW, you can use the DECL_BOOLEAN_ACCESSORS convenience functions if you haven't
seen them yet.

+1. Please turn this into smi "flag" field + boolean "has_handler" accessor as
Jakob suggested. It will make caller code look nicer.

Done.
