Yes. How about this:
[[Getter]] A zero-argument function that is called each time the
property is read (via a [[Get]] operation), to return the
result of the read.
[[Setter]] A one-argument function that is called with the written
value each time the property is written (via a
[[ThrowablePut]] operation).
The references to [[Get]] and [[ThrowablePut]] are needed because it is
possible for host objects to override any of the internal methods in such
a way that [[Getter]] and [[Setter]] are not used, even when there is a
property read (call to GetValue) or write (call to PutValue).
