Struct NullInToml 

pub struct NullInToml { /* private fields */ }

Nulls survived into a document being converted to TOML.

A genuine impossibility in user data, so it is an error rather than a silent drop. Provenance is filled in after the fact by looking each path up in the layers that went into the merge — not threaded through the merge.
