Not exactly in fact - unless I messed something. There are 2 problems 
here: a more flexible tuple unpacking, *and* a lambda in disguise. 
Actually, I'd go + 1 for the first, -1 for the second

For the second part, yes. Not for the first one.

...and without list comprehensions, __call__ and other special methods, 
descriptors, metaclasses, first class functions, builtin datatypes like 
lists and dicts, exceptions, dynamic typing, garbage collection,  etc 
too. Hurray, let's all happily program in assembly !-)
