I don't think for_constructor is necessary:
you can just check method.is_constructor

'method' is an IdlOperation/IdlAttribute/.. object, so that wouldn't quite work.
I've switched to doing a bit of type testing with .name, however - hope that
addresses the concern.

Got it!
It does -- much clearer, thanks!

I think you can push this into v8_utilities.scoped_name:
just add:
if definition.is_constructor:
    return '%s::%s' % (cpp_name(interface), 'create')
...to it.

Also, single quotes please.

For the same reasons as the above comment, attribute isn't present on this
object. Have tweaked the code a bit to allow reuse of scoped_name() though,
again consulting .name.

+    else:
+        cpp_method_name = v8_utilities.scoped_name(interface, method, v8_utilities.cpp_name(method))
     return '%s(%s)' % (cpp_method_name, ', '.join(cpp_arguments))
