| Updated patch with: * fix error in islice function name * made n=None default second argument for consume(iterator, n=None) cause it provides specific behavior when n is None which can be assumed as default for function |

| How are popular the proposed recipes? Not every possible combination of functions is worth to mention in the documentation. |

| It's hard to evaluate how popular given recipes, but: * drop is opposite to take, so it's as popular as take * the same situation with splitat, splitby - it's one case of partition that's hard to write each time with enumerator (partition is already in documentation) * takelast, droplast was added cause itertools.islice doesn't support negative indices (which is ok). both functions have not obvious implementation - I'm sure that recipes will be good example for users how to work with iterators even if concrete functions aren't so widely-spreaded |

| I will add drop() to the recipes and possibly take_last() which I would rename add tail(). Sorry, I don't have interest in the others. I don't find them instructive or very useful. |

| In the end, I decided to add a variant of take_last(). Thank you for the suggestion. |
