Version 3.11
------------
Fixed some minor bugs related to re flags and token order.
Added a set_lexpos() method to grammar symbols.
Mostly minor bug fixes and small code cleanups.
Version 3.10
------------
Changed grammar signature computation to not involve hashing
functions. Parts are just combined into a big string.
Fixed Issue 101: Incorrect shift-reduce conflict resolution with
precedence specifier.
PLY was incorrectly resolving shift-reduce conflicts in certain
cases. For example, in the example/calc/calc.py example, you
could trigger it doing this:
calc > -3 - 4
1 (correct answer should be -7)
calc >

Version 3.9
-----------
Exposed the parser state number as the parser.state attribute
in productions and error functions. For example:
def p_somerule(p):
'''
rule : A B C
'''
print('State:', p.parser.state)
May address issue 65 (publish current state in error callback).
Fixed Issue 88. Python3 compatibility with ply/cpp.
Fixed Issue 93. Ply can crash if SyntaxError is raised inside
a production. Not actually sure if the original implementation
worked as documented at all. Yacc has been modified to follow
the spec as outlined in the CHANGES noted for 11/27/07 below.
Fixed Issue 97. Failure with code validation when the original
source files aren't present. Validation step now ignores
the missing file.
Minor fixes to version numbers.
