An hybrid list-tuple concatenation is not allowed
[]+(1, 2)
Traceback (most recent call last):

TypeError: can only concatenate list (not "tuple") to list
hence I was expecting (*) that the following code raises a TypeError :
x = []
x += (1, 2)
x
[1, 2]
Any explanation ?
>>> seq = [1,2]
>>> seq.extend((3,4))
>>> seq+= {5, 6} # the order of extending is not determined
>>> seq
[1, 2, 3, 4, 5, 6]
