# list_c

### Synopsis

    template<
          typename T
        , T C1 = implementation-defined
        , T C2 = implementation-defined
        , ...
        , T CN = implementation-defined
        >
    struct list_c
    {
    };

### Description

Similary to `vector_c`, `list_c` is a shorcut interface whose whole purpose is to make the creation of a `list` of Integral Constants less verbose:

    typedef list_c<unsigned long,-1,0,1,1,-1,0,0,1,-1> data;

If `list_c` didn't exist, instead of the above line you would have to write this:

    typedef list<
          integral_c<unsigned long,-1>
        , integral_c<unsigned long,0>
        , integral_c<unsigned long,1>
        , integral_c<unsigned long,1>
        , integral_c<unsigned long,-1>
        , integral_c<unsigned long,0>
        , integral_c<unsigned long,0>
        , integral_c<unsigned long,1>
        , integral_c<unsigned long,-1>
        > data;
