-/**
- * Wrapper for compile-time-constant strings.
- *
- * Const is a wrapper for strings that can only be created from program
- * constants (i.e., string literals).  This property relies on a custom Closure
- * compiler check that {@code goog.string.Const.from} is only invoked on
- * compile-time-constant expressions.
- *
- * Const is useful in APIs whose correct and secure use requires that certain
- * arguments are not attacker controlled: Compile-time constants are inherently
- * under the control of the application and not under control of external
- * attackers, and hence are safe to use in such contexts.
- *
- * Instances of this type must be created via its factory method
- * {@code goog.string.Const.from} and not by invoking its constructor.  The
- * constructor intentionally takes no parameters and the type is immutable;
- * hence only a default instance corresponding to the empty string can be
- * obtained via constructor invocation.
- *
- * @see goog.string.Const#from
- * @constructor
- * @final
- * @struct
- * @implements {goog.string.TypedString}
