+// The returned logger writes all records with level >= slog.LevelError as

+// logger := <some Logger with 0 as verbosity level>
+// slog.New(ToSlogHandler(logger.V(10))).Error(...) -> logSink.Error(...)

+// The level of all other records gets reduced by the verbosity
+// level of the Logger and the result is negated. If it happens
+// to be negative, then it gets replaced by zero because a LogSink
+// is not expected to handled negative levels:

+// slog.New(ToSlogHandler(logger)).Debug(...) -> logger.GetSink().Info(level=4, ...)
+// slog.New(ToSlogHandler(logger)).Warning(...) -> logger.GetSink().Info(level=0, ...)

+// SlogSink is an optional interface that a LogSink can implement to support
+// logging through the slog.Logger or slog.Handler APIs better. It then should
+// also support special slog values like slog.Group. When used as a
+// slog.Handler, the advantages are:
+//
+// - stack unwinding gets avoided in favor of logging the pre-recorded PC,
+// as intended by slog
+// - proper grouping of key/value pairs via WithGroup
+// - verbosity levels > slog.LevelInfo can be recorded
+// - less overhead
+//
+// Both APIs (Logger and slog.Logger/Handler) then are supported equally
+// well. Developers can pick whatever API suits them better and/or mix
+// packages which use either API in the same binary with a common logging
+// implementation.
+//
+// This interface is necessary because the type implementing the LogSink
+// interface cannot also implement the slog.Handler interface due to the
+// different prototype of the common Enabled method.
+//
+// An implementation could support both interfaces in two different types, but then
+// additional interfaces would be needed to convert between those types in FromSlogHandler
+// and ToSlogHandler.
