The core expects to be able to extract a struct value from a gdb.Value.
So, you would need to create the struct value when constructing a new
Value from Python.  That's the only tricky bit I can think of.

In other places I've just relied on duck typing... e.g., for the
pluggable "backtrace", some filters return objects that supply all the
frame methods.  I assume that isn't enough in your case since
presumably you want the core to convert your sub-Value to a gdb value
automatically.  Maybe there's some other way we could solve that.
