Change https://go.dev/cl/580495 mentions this issue: log/slog: Add WithAttrs and Logger.WithAttrs

CC @jba

It's unfortunate that you can't write logger = logger.With(attrs...). But you can get the same effect with

for _, a := range attrs {
    logger = logger.With(a)
}

That is less efficient, but the question is whether it comes up often enough to matter.

While the suggested workaround using a loop to iterate over the attributes and apply them individually with logger.With(a) is indeed functional, as you noted, it may introduce some inefficiency, particularly in scenarios where a large number of attributes need to be logged.

Considering your point about whether the inefficiency of the loop comes up often enough to matter, I think it's important. However, introducing a dedicated function like WithAttrs would provide a more streamlined and efficient solution for handling attribute-based logging, ultimately improving code readability and maintainability.

Just as LogAttrs offers a specialized solution for logging structured data with attributes, a dedicated WithAttrs function would serve a similar purpose for attribute-based logging within the context of With.
