What if I want to chain an infinite list of iterables? Shouldn't itertools.chain be built to handle that?

Raymond already suggested a four-line function that does exactly that.

Create your own personal-library modules containing the functions you find useful as building blocks, and when you have a large sw base using them, present your building blocks along with their use cases as arguments for inclusion in the standard library.

I don't think it is a problem to accept only the second case you paste and produce TypeError on the others.

It would break compatibility with the current uses of itertools.chain . I like it (and have used it) as it is.
