Some time ago I've posted question about binary pp sequences to this list. And 
you were so kind to supply me with this macro:

# define BINARY_SEQ_TO_SEQ(seq) BINARY_SEQ_TO_SEQ_I(seq)
# define BINARY_SEQ_TO_SEQ_I(seq) BOOST_PP_CAT(BINARY_SEQ_TO_SEQ_A seq, 0)
# define BINARY_SEQ_TO_SEQ_A(x, y) ((x, y)) BINARY_SEQ_TO_SEQ_B
# define BINARY_SEQ_TO_SEQ_B(x, y) ((x, y)) BINARY_SEQ_TO_SEQ_A
# define BINARY_SEQ_TO_SEQ_A0
# define BINARY_SEQ_TO_SEQ_B0

Thans again for wonderfull library and great help on this mailing list.
