Detailed Description

The stored form of a return_policy annotation: a return-value policy, optionally scoped to some languages.

Like a scoped weld_as it pairs a language mask (0 == all languages) with its payload — here the welder::rv_kind rather than a name — so a callable can take one policy in Python and another (or none) in Lua. Not templated, so the reflection layer reads it with the plain annotations_of_with_type idiom.
