I can see it together with partial, yes, that's when it can become a bit cleaner. Another reason why I use map is when I want to use multiprocessing or multithreading (with IO heavy functions). But on a fine grained level of code I find it really hurts readability compared to comprehensions.

Or this:

    def to_strings(seq):
        return map(str, seq)

Generally, when the operation I'm applying to each element happens to already be a named function, I find "map(f, seq)" preferable to "(f(x) for x in seq)".
