||
* ElementTree/cElementTree (Fredrik Lundh)
|
||
* msilib (Martin von Loewis)
|
||
* pysqlite (Gerhard Haering)

|
||
|
||

||
* http://python.org/sf/1474677 foo(b=1, 2) doesn't raise SyntaxError
|
||
|
||
* eval(str(-sys.maxint - 1)) should produce an int, not long.
|
||
when a constant it should not be stored in co_consts
|
||
|

* string constants that are not assigned are in byte code
|
||
def foo():
|
||
"docstring"
|
||
"not a docstring"
|
||
the constant (not a docstring) should not be stored in co_consts
