Joris Van den Bossche updated ARROW-17821:
------------------------------------------
Description:
If column A has list\(x), column B has list\(y), column C has list(z), I'd like
to be able to create D = zip(A,B,C) where D would be list(\{ A: x, B: y, C: z}).
x, y, z are types in the example, type of the resulting is D is list(struct).
Other features to consider:
* Zipping list(struct) with list\(x) or list(struct) with list(struct) should
be able to merge
* Zipping A,B into a Map with keys from A, values from B
