Oh I see.  So it doesn't help avoid conflicts in the module importing 
weakref, but it helps avoid them in the modules that import the modules 
that import weakref.

Well anyway, the code probably needs big changes to be a good WeakRef 
class for D2 anyway, so I might as well just ditch the alias and use 
char[] directly.

But anyway, no one has given me access to scrapple.

Thanks for the feedback.
