What do you mean? Here are some examples where this notation is used in Rev. 19: + 9.1.15.1 [[Call]] (thisArgument, argumentsList) + Step 9.b.i.1 Set thisValue to calleeRealm.[[globalThis]]. + 9.2.2.1 [[DefineOwnProperty]] (P, Desc) + Step 3.b Let oldLen be oldLenDesc.[[Value]]. + 16.6.2.2 Runtime Semantics: LabelEvaluation + Step 2.f ... let V = stmt.[[value]] + 14.1.13 Runtime Semantics: IndexedBindingInitialisation + FunctionRestParameter : ... BindingIdentifier + Step 3 Let argumentsLength be status.[[value]]. There acutlly appears to be only one occurance of "Set ... to ...". Other occurrences say "Let ... be ...", so I should have used that terminology. Apologies. I think I have my answer, though. Internal implies own. Thanks!
