A TypeList is used instead of declaring an enum so that the integer values are clearly defined and extension of the list is robust.

An enumeration value for a type is given by: NumericEnum< Type >::value . Thus a switch statement for a numeric type is formed as follows.

switch( my_value ) {
case NumericEnum< int >::value : ... ; break ;
case NumericEnum< float >::value : ... ; break ;
case NumericEnum< double >::value : ... ; break ;
default: ... ;
}
