| description: Temporal.Instant.prototype meets the requirements for built-in objects |
| info: | |
| Built-in functions that are not constructors do not have a "prototype" property unless |
| otherwise specified in the description of a particular function. |
| |
| Unless specified otherwise, a built-in object that is callable as a function is a built-in |
| function object with the characteristics described in 10.3. Unless specified otherwise, the |
| [[Extensible]] internal slot of a built-in object initially has the value true. |
| |
| Unless otherwise specified every built-in function and every built-in constructor has the |
| Function prototype object [...] as the value of its [[Prototype]] internal slot. |
