The difference IMHO is, that this is not a generic approach. It's a bit
like replacing templates with macros. I haven't seen any convincing
arguments against the code I showed, which *is* generic IMHO, but as I
don't have the background of the "long saga" you mentioned, I think I'm
not the right one to say what's the best way to go.
