Krisztian Szucs commented on ARROW-9997:
----------------------------------------
I'd also prefer the mapping API, but {{.as_py()}} should not fail in any
circumstance. If we keep the mapping API and return with a dict from
{{.as_py()}}, then it is going to fail if there are duplicate field names.
If we add a mapping-like interface which tolerates duplicate keys end we
implement it for both the StructScalar objects and for the one which is
returned by StructScalar.as_py() then it could work.

> {{StructScalar}} currently extends an abstract Mapping interface. Since the
> type allows duplicate field names we cannot provide that API.
