Is there anything anyone has on the gotchas for non-templated 
stuff?  I am sure this would be of more general interest, since 
everybody likely has some legacy code they want to connect with.

I get the impression the subset of C++ people often restrict 
themselves to tends not to favour heavy metaprogramming, but I 
don't know how much template stuff they actually tend to do at 
this place.  (Will find out).
