But /value/ hasn't been defined.
Maybe missing an earlier step:
Let /value/ be Desc.[[Value]]

Set the [[Get]] internal method of A as specified in 8.4.6.1.
Set the [[Set]] internal method of A as specified in 8.4.6.2.
Change section numbers to 8.4.6.4, 8.4.6.5.

8.4.6.10 / step 2
Let O be the result of calling ToObject with the this value as its argument.
This is doubly odd, because it overwrites the parameter 'O', and also references
the 'this' value, which isn't normally defined for abstract operations.
Also,
8.4.2 / para 4
Exotic Array objects provide an alternative definition for the
[[DefineOwnProperty]] internal methods.
