ClassExpression : class BindingIdentifieropt ClassTail
1. If BindingIdentifieropt is not present, let className be undefined.
2. Else, let className be StringValue of BindingIdentifier.
3. Let value be the result of ClassDefinitionEvaluation of ClassTail
with argument className.
[...]
14.5.14 Runtime Semantics: ClassDefinitionEvaluation
21. For each ClassElement m in order from methods
a. If IsStatic of m is false, then
b. Else,
Let status be the result of performing PropertyDefinitionEvaluation for
m with arguments F and false.
[...]
14.3.8 Runtime Semantics: DefineMethod
MethodDefinition : PropertyName ( StrictFormalParameters ) { FunctionBody }
[...]
6. Let closure be FunctionCreate(kind, StrictFormalParameters, FunctionBody,
scope, strict). If functionPrototype was passed as a parameter then pass its
value as the functionPrototype optional argument of FunctionCreate.
