This is very bad to me, I will need to write some cumbersome syntax as
follow:
for d in self.data:
m = self.macro_parser.match (d)) != None ):
if (m == None):
m_nat = self.a_parser.match (d)
if (m_a == None):
m_rdr = self.b_parser.match (d)
if (m_b == None):
m_c = self.c_parser.match (d)
if (m_c == None):
m_d = self.d_parser.match (d)
if (m_d == None):
m_e = self.e_parser.match (d)
if (m_e == None):
