It doesn't seem very intuitive (doesn't follow proper English
phrasing, for instance) and I don't think it's a common enough
situation to warrant adding a special syntax for it. But if you really
want it, you could use something like this:

def double_for(iterable):
    for outer in iterable:
        yield from outer

for c in double_for(Names):
    print(c)

But I don't think this is any clearer than making the loops explicit.
