Raymond Hettinger added the comment:
I've looked into this a bit more. Even in Haskell, it seems that use case is
for str.join() which we already have. I don't see intersperse() in any other
functional languages. That suggests that its use cases aren't sufficiently
common to warrant adding
New submission from Alexander Boyd:
Itertools would benefit greatly from a function (which I've named intersperse,
after Haskell's equivalent) for yielding the items of an iterator with a given
value placed between each. Sort of a str.join-like function, but for arbitrary
sequences.

What is the use case for interspersing values? I've not run across anything
like it ever before.
