Boldly Go

Covers the difference between slog.Group and slog.GroupAttrs in Go's structured logging package, noting that GroupAttrs is more efficient but only accepts slog.Attr values with no mixed form. Provides a practical toAttrs helper function that replicates slog's internal logic for converting variadic any arguments (including both string key/value pairs and slog.Attr values) into a []slog.Attr slice, useful when building custom slog wrapper utilities.

slog.GroupAttrs

<p>A wrapper that converts Group’s mixed …any form into []slog.Attr is useful, but that helper effectively becomes part of the logging API contract. Table tests for dangling keys, non-string keys, and prebuilt Attr values would help ensure its behavior stays aligned with slog’s normalization across Go releases.</p>
