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.

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