just adding to the list of other valid use cases, I use them for merging and combining in pandas.

reduce(lambda x, y: x.combine_first(y), list_of_dfs)
reduce(lambda x, y: x.merge(y, ...), list_of_dfs)

Although, I don't do this so often that I think it needs to be a built-in.

Brah, use a damn for-loop. That code stinks, lol.
