description: Tests that Temporal.Instant.from 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.

description: Temporal.Instant.from.length is 1
info: |
Every built-in function object, including constructors, has a "length" property whose value is
an integer. Unless otherwise specified, this value is equal to the largest number of named
arguments shown in the subclause headings for the function description. Optional parameters
(which are indicated with brackets: [ ]) or rest parameters (which are shown using the form
«...name») are not included in the default argument count.
Unless otherwise specified, the "length" property of a built-in function object has the
attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: true }.

info: |
Every built-in function object, including constructors, that is not identified as an anonymous
function has a "name" property whose value is a String. Unless otherwise specified, this value
is the name that is given to the function in this specification.
Unless otherwise specified, the "name" property of a built-in function object, if it exists,
has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: true }.
