[Development] Question about QtDeclarative Internals

Hello,

In QtDeclarative, can a QV4::ReturnedValue or a QV4::Value be converted
into an ExecutableCompilationUnit?

I'm trying to work on a patch for QJSEngine to allow importing modules from
C++ (similar to Node.js: import fs from "fs")
The planned method is something along the lines of:
void QJSEngine::registerModule(const QString &moduleName, const QJSValue
&value)

I can see that behind the scenes, loadModule compiles a URL to an
ExecutableCompilationUnit, then saves it to a list of modules for future
lookup.
I thought the easiest way to do what I need is to convert a QJSValue to an
internal QV4::Value, and from there into an ExecutableCompilationUnit.
Is there any way of doing that?

Thanks.
