You can't have multiple instantiations of templated nested functions either. 
IIRC, I created a bug report on it, and Walter closed it as won't fix, but I 
don't remember what his reasoning was, though IIRC, he was essentially of the 
opinion that nested functions didn't need to have the full capabilities of 
normal functions. I assume that that simplifies their implementation, but I 
don't know.
