You could skip this conditional if |internal_namespace| was either '' (default)
or '::symbol' (from caller) and just make the call

{{cpp_class}}V8Internal{{internal_namespace}}::{{method.name}}Method{{world_suffix}}(info);

OTOH, I'm not entirely sure why we bother with the explicit namespace here at
all; just calling {{method.name}}Method(info) would work too.

Done.
I introduced a new namespace to avoid name conflict against a string-keyed
method with the same name.
In this case, interfaces can have usual 'iterator' method.

Thanks.
Yes, adding the namespace is all good.

+    {{cpp_class}}V8Internal::{{internal_namespace}}::{{method.name}}Method{{world_suffix}}(info);
     {% else %}
     {{cpp_class}}V8Internal::{{method.name}}Method{{world_suffix}}(info);
     {% endif %}
