- /** \def BOOST_VMD_ENUM(...)
- \brief Converts a sequence to comma-separated elements which are the elements of the sequence.
- ... = Variadic parameters.
-
- The first variadic parameter is required and is the sequence to convert.
-
- Further optional variadic parameters can be return type parameters. Return type
- parameters allow each element in the sequence to be converted to a two-element
- tuple where the first tuple element is the type and the second tuple element
- is the element data.
-
- The BOOST_VMD_RETURN_NO_TYPE, the default, does not return the type as part of each
- converted element but just the data. All of the rest return the type and data as the
- two-element tuple. If BOOST_VMD_RETURN_TYPE is specified the specific type of the element
- is returned in the tuple. If BOOST_VMD_RETURN_TYPE_ARRAY is specified an array type is
- returned if the element is an array, else a tuple type is returned if the element is a tuple,
- else the actual type is returned for non-tuple data. If BOOST_VMD_RETURN_TYPE_LIST is specified
- a list type is returned if the element is a list, else a tuple type is returned if the element
- is a tuple, else the actual type is returned for non-tuple data. If BOOST_VMD_RETURN_TYPE_TUPLE
- is specified a tuple type is returned for all tuple-like data, else the actual type is returned
- for non-tuple data. If more than one return type optional parameter is specified the last one
- specified determines the return type.
-
- returns = Comma-separated data, otherwise known as variadic data.
- If the sequence is empty the variadic data is empty. If an
- optional return type other than BOOST_VMD_RETURN_NO_TYPE
- is specified the type and the data of each element is
- returned as part of the variadic data. Otherwise just the data
- of each element is returned, which is the default.
