Could we use an enum class instead of a boolean? I understand this is only used in generated code but the call sites are really not very readable.

return !impl.isSupportedPropertyIndex(index.value()); ? Why the ternary?

typo: algorithm

> Source/WebCore/bindings/scripts/CodeGeneratorJS.pm:856

Why the ternary?

> +    // Bindings support functions

Missing period at the end

Ok.

Just cause it was how the spec was worded. I'll collapse it.
