Why create this method instead of just using Write?
Since this package and type is public, we'd prefer to not introduce new
methods if possible.

Just figured it helped avoid checking for errors via Write() which were known-impossible, but not worth disrupting the larger picture just for that (and in a previous, unsubmitted version, I was calling it from more than one site, so it was a mild ergonomic improvement).

Use of Write here should be fine

LGTM besides lack of AppendReflected support.

Since we're treating this as an optimization, I'm in favor of doin it to AppendReflected too.
It already supports nil entries inside slices. https://play.golang.org/p/bZb6t58qhpy

This prepares release v1.13.0 with #758 in it.

This adds support for building fields from pointers to primitive types we already accept. These new field constructors accept and handle `nil` values in addition to the non-nil primitive values. For nil values, we fall back to the behavior of `zap.Reflect(..)`, which we optimize for in the JSON encoder so that we don't use `encoding/json` just to build the string `"null"`. Resolves uber-go#753
This prepares release v1.13.0 with uber-go#758 in it.
Fixes #753 by exporting util functions to handle nillable primitives. The version here uses
Reflect()under the hood to encodenil, and makes corresponding changes injson_encoder.goto efficiently handle encodingnilfield values.
