/** \def BOOST_VMD_IS_TYPE(sequence)

    \brief Tests whether a sequence is a VMD type.

    sequence = a possible VMD type
    
    returns = 1 if the sequence is a VMD type, 
              0 if it is not.
    
    If the sequence is not a VMD data type this macro could lead to
    a preprocessor error. This is because the macro
    uses preprocessor concatenation to determine if the sequence
    is an identifier once it is determined that the sequence does not
    start with parentheses. If the data being concatenated would
    lead to an invalid preprocessor token the compiler can issue
    a preprocessor error.
