/** \def BOOST_VMD_ASSERT_IS_LIST(sequence)
\brief Asserts that the sequence is a Boost PP list.
The macro checks that the sequence is a Boost PP list.
If it is not a Boost PP list, it forces a compiler error.
The macro normally checks for a Boost PP list only in
debug mode. However an end-user can force the macro
to check or not check by defining the macro
BOOST_VMD_ASSERT_DATA to 1 or 0 respectively.
sequence = a possible Boost PP list.
returns = Normally the macro returns nothing.
If the sequence is a Boost PP list, nothing is
output.
For VC++, because there is no sure way of forcing
a compiler error from within a macro without producing
output, if the sequence is not a Boost PP list the
macro forces a compiler error by outputting invalid C++.
For all other compilers a compiler error is forced
without producing output if the parameter is not a
Boost PP list.
