--- Comment #1 from Ross Kirsling <ross.kirsling at sony.com> ---
Not certain whether it's problematic, but I have noticed one interesting thing:

If the imported module throws on evaluation, we never actually return to the JS-side callsite for module evaluation:
https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/builtins/ModuleLoader.js#L315

...even though an encoded jsNull is returned from the CPP side in the usual way:
https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/runtime/JSModuleLoader.cpp#L488
