        list is a Forward
        Sequence of heterogeneous typed data built on top of cons. It is more efficient than
        vector
        when the target sequence is constructed piecemeal (a data at a time). The
        runtime cost of access to each element is peculiarly constant (see Recursive Inlined Functions).

template < typename T0 = unspecified , typename T1 = unspecified , typename T2 = unspecified ... , typename TN = unspecified > struct list;
For C++11 compilers, the variadic function interface has no upper bound.
        For C++03 compilers, the variadic class interface accepts 0
        to FUSION_MAX_LIST_SIZE elements,
        where FUSION_MAX_LIST_SIZE
        is a user definable predefined maximum that defaults to 10.
        Example:
      
list<int, char, double>
        You may define the preprocessor constant FUSION_MAX_LIST_SIZE
        before including any Fusion header to change the default. Example:
      
#define FUSION_MAX_LIST_SIZE 20
