/**
 * Tagged template literal function with type-safe interpolated values.
 *
 * ###
 *
 * Constructs and caches an optimized template function for the given template
 * string and interpolated expressions, which can be used to render arbitrary
 * data payloads into the template at runtime.
 *
 * ### Caching
 *
 * The template function is cached for the given template string and values, so
 * that the same _template string with the same values_[^1] will always return
 * the same function instance. This allows for efficient reuse of the template
 * and its compiled function, and avoids unnecessary recompilation overhead.
 *
 * **Note**: no strong references are maintained to cached templates, meaning
 * the runtime can garbage collect a template if it is no longer accessible.
 *
 * [^1]: The template string and values are compared by reference, so "the
 *       same" means quite literally the same object instances, not just
 *       equivalent strings with the same content, so calling `template``foo``
 *       twice will not take advantage of this caching feature.
 *
 * To render the template to a string, call the returned function with the
 * desired data payload for interpolation, and it will return the template
 * string with the payload's values injected into the appropriate locations.
 *
 * ### Template Expressions and Interpolations
 *
 * Expressions that match a key in the context object will be replaced with the
 * associated value; if the value is a function (or is a key for a method in
 * the context object), it will be called with the context object as the `this`
 * value (and as the first argument).
 *
 * @param tpl The template string array.
 * @param values Interpolated values/expressions to inject into the template.
 * @returns A cached template function that can be passed a payload to render.
 * @example
 * ```ts
 * import { template } from "@nick/tpl";
 *
 * class User {
 *   static readonly greet = template<User>`Hello, ${"name"}!`;
 *
 *   constructor(public name: string, public age: number) {}
 *
 *   readonly greet = template<User>`Hello, ${"name"}!`.bind(this);
 * }
 *
 * const user = new User("Alice", 42);
 * console.log(User.greet(user)); // "Hello, Alice!"
 * console.log(user.greet()); // "Hello, Alice!"
 *
 * user.name = "Bob";
 * console.log(User.greet(user)); // "Hello, Bob!"
 * console.log(user.greet()); // "Hello, Bob!"
 * ```
