-- Syntax for type-checking tables:
--
-- A type-checking table describes typing data for a value.
-- Any key starting with an underscore has a special meaning:
-- _type (string) is the Lua type of the value. Default is "table".
-- _mandatory (boolean) indicates if the value is a mandatory key in its container table. Default is false.
-- For "string" types only:
-- _pattern (string) is the string-matching pattern, valid for string types only. Default is ".*".
-- For "table" types only:
-- _any (table) is the type-checking table for unspecified keys, recursively checked.
-- _more (boolean) indicates that the table accepts unspecified keys and does not type-check them.
-- Any other string keys that don't start with an underscore represent known keys and are type-checking tables, recursively checked.
