In attempting to upgrade from version 2.3 to 2.5 of Ply I found a
difference which does not seem to be mentioned in the documentation.
Running the code below produces a different answer on 2.3 and 2.5. On
2.3 it prints A, on 2.5 it prints B. Reading the documentation implies
that 2.3 is correct and 2.5 is wrong.
from ply import lex, yacc
t_A = 'A'
t_B = 'B'
t_C = 'C'
tokens = ('A', 'B', 'C')
the_lexer = lex.lex()
def p_start(t):
'''start : A nest C'''
def p_nest(t):
'''nest : B'''
print t[-1]
the_parser = yacc.yacc(debug = False, write_tables = False)
the_parser.parse('ABC', the_lexer)
