### #define BOOST_PP_LIST_TO_TUPLE(LIST)

Converts the list to a tuple.

For example,

    BOOST_PP_LIST_TO_TUPLE(BOOST_PP_TUPLE_TO_LIST(3,(A,B,C)))

expands to `(A,B,C)`.

### Note

- The supported size of the list being converted to a tuple is limited by BOOST_PP_LIMIT_MAG rather than BOOST_PP_LIMIT_TUPLE.

### Test

- list_test.cpp

### #define BOOST_PP_LIST_TO_TUPLE_R(R,LIST)

Can be used inside BOOST_PP_FOR() (see for an explanation of the R parameter).
