New submission from Thomas Wouters <[EMAIL PROTECTED]>:
The attached patch adds the missing *-unpacking generalizations.
Specifically:
>>> a, b, *c = range(5)
>>> *a, b, c = a, b, *c
>>> a, b, c
([0, 1, 2], 3, 4)
>>> [ *a, b, c ]
[0, 1, 2, 3, 4]
>>> L = [ a, (3, 4), {5}, {6: None}, (i for i in range(7, 10)) ]
>>> [ *item for item in L ]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Also, yielding everything from an iterator:
>>> def flatten(iterables):
... for it in iterables:
... yield *it
...
>>> L = [ a, (3, 4), {5}, {6: None}, (i for i in range(7, 10)) ]
>>> flatten(L)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
