esid: prod-FieldDefinition
features: [class-static-methods-private, class]
flags: [generated]

MethodDefinition :
get ClassElementName () { FunctionBody }
set ClassElementName ( PropertySetParameterList ) { FunctionBody }
ClassTail : ClassHeritage { ClassBody }
...
33. If PrivateBoundIdentifiers of ClassBody contains a Private Name P such that P's [[Kind]] field is either "method" or "accessor" and P's [[Brand]] is F,
a. PrivateBrandAdd(F, F).
34. For each item fieldRecord in order from staticFields,
a. Perform ? DefineField(F, field).
PrivateFieldGet (P, O)
1. Assert: P is a Private Name.
2. If O is not an object, throw a TypeError exception.
3. If P.[[Kind]] is "field",
...
4. Perform ? PrivateBrandCheck(O, P).
5. If P.[[Kind]] is "method",
...
6. Else,
a. Assert: P.[[Kind]] is "accessor".
b. If P does not have a [[Get]] field, throw a TypeError exception.
c. Let getter be P.[[Get]].
d. Return ? Call(getter, O).
PrivateBrandCheck(O, P)
1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
a. Throw a TypeError exception.
