I often use generators, and itertools.chain on them.
What about providing something like the following:
a = (n for n in range(2))
b = (n for n in range(2, 4))
tuple(a + b) # -> 0 1 2 3
You know you can do `tuple(*a, *b)` , right?
The problem with the "*" notation is that it will actually render the
iterable
contents eagerly - unlike something that would just chain them.
But for creating tuples, it just works.
Even the tuple constructor is not needed.
>>> *a, *b
(0, 1, 2, 3)
