I'm really not fond at all of the "recipes" section, at least under its
current incarnation: it's nice to have examples of composing itertools
functions to build more specialized or higher-level tools, but recipes
functions should be available in itertools or a submodule: the work has
been done already, it's wasteful and annoying to have to copy/paste
these functions to some arbitrary location every time they are needed,
that's what libraries are for.

At least there's more_itertools on pypy, but I think one should not need
a third-party package for things functions which are defined (though not
useable) in the standard library itself.
