    ClassElement : MethodDefinition
      1. Return ClassElementEvaluation of MethodDefinition with arguments ! Get(homeObject, "prototype"),enumerable, and "prototype".

    ClassElement : static MethodDefinition
      1. Return ClassElementEvaluation of MethodDefinition with arguments homeObject, enumerable and "static".

    MethodDefinition : ClassElementName( UniqueFormalParameters ) { FunctionBody }
      1. Let methodDef be DefineMethod of MethodDefinition with argument homeObject.
      2. ReturnIfAbrupt(methodDef).
      3. Perform ? DefineOrdinaryMethod(methodDef.[[Key]], homeObject, methodDef.[[Closure]], _enumerable).

    ClassElement : MethodDefinition
    ClassElement : static MethodDefinition
      1. Perform ? PropertyDefinitionEvaluation with parameters object and enumerable.
      2. Return empty.
