SomeField(many=True) vs List(SomeField())

[jtrakk]

I've always used List(SomeField()) and haven't really understood the purpose of SomeField(many=True). Is there a guideline for when I'd want to use SomeField(many=True) instead of List(SomeField())? Thanks.

See #779 ; we are considering deprecating Nested(many=True) in favor of List(Nested()). It used to be Nested(many=True) had better error reporting behavior and was more performant, but in marshmallow 3 they will be in parity with each other.
