Great, thank you !

I had a quick look, it's just what I had in mind. I can insert it almost
verbatim, and redefine the existing classes as a specialization with JSValue
as a type.

Thank you, this will save me a lot of typing :-)

This weekend I will do the refactoring. 
This, together with the support for linking resources, is reason enough to make 
a new release, even without the fgl and system.generics.* units...

Exciting times :-)
