I agree, that's why MY implementation would call seq.flatten() on all sub-sequences THEREBY allowing each subtype to define it's own flatten behavior. Of course the default behavior of the SequenceBase#flatten would be to flatten everything.

So...

flatten([None, 23, [1, 2, 3], (2, 3), ["spam", "ham"]])

would return

[None, 23, 1, 2, 3, (2, 3), "spam", "ham"]

? I think that's even more unexpected.
