/**
 * Creates a `Context` service key.
 *
 * **When to use**
 *
 * Use when you need to define a context service key for a dependency that must
 * be provided by the surrounding context.
 *
 * **Details**
 *
 * Call `Context.Service("Key")` for a function-style key, or use the two-stage
 * form `Context.Service<Self, Shape>()("Key")` for class-style service
 * declarations. The returned key can be yielded as an Effect and passed to
 * `Context.make`, `Context.add`, and the Context getter functions.
 *
 * **Gotchas**
 *
 * The string key is the runtime identity of the service. Reusing the same key
 * string for unrelated services makes them occupy the same slot in a
 * `Context`.
 *
 * **Example** (Creating service keys)
 *
 * ```ts
 * import { Context } from "effect"
 *
 * // Create a simple service
 * const Database = Context.Service<{
 *   query: (sql: string) => string
 * }>("Database")
 *
 * // Create a service class
 * class Config extends Context.Service<Config, {
 *   port: number
 * }>()("Config") {}
 *
 * // Use the services to create contexts
 * const db = Context.make(Database, {
 *   query: (sql) => `Result: ${sql}`
 * })
 * const config = Context.make(Config, { port: 8080 })
 * ```

/**
 * Creates a context key with a default value.
 *
 * **When to use**
 *
 * Use when you need to define a context key with a lazily computed default
 * value.
 *
 * **Details**
 *
 * `Context.Reference` allows you to create a key that can hold a value. You
 * can provide a default value for the service, which will automatically be used
 * when the context is accessed, or override it with a custom implementation
 * when needed. The default value is computed lazily and cached on the
 * reference.
 *
 * **Example** (Creating references with default values)
 *
 * ```ts
 * import { Context } from "effect"
 *
 * // Create a reference with a default value
 * const LoggerRef = Context.Reference("Logger", {
 *   defaultValue: () => ({ log: (msg: string) => console.log(msg) })
 * })
 *
 * // The reference provides the default value when accessed from an empty context
 * const context = Context.empty()
 * const logger = Context.get(context, LoggerRef)
 *
 * // You can also override the default value
 * const customContext = Context.make(LoggerRef, {
 *   log: (msg: string) => `Custom: ${msg}`
 * })
 * const customLogger = Context.get(customContext, LoggerRef)
 * ```
 *
 * @see {@link Service} for required services without default values
 *
 * @category references
 * @since 3.11.0
