Maybe it's supposed to. The spec for .stringof is completely different 
to what's implemented.

But anyway...

Getting the fully qualified name is currently possible (since about 
D0.150) but it's a bit disgusting to do, and I can't really recommend 
it.  My old meta.nameof module did the job.
If you pass the module name as a template alias parameter, the fully 
qualified name appears in the mangled name. You just need to demangle it 
and extract the module name.
