In general, I agree that that's a good policy. How expensive would you 
consider templated functions which aren't used to be with regards to that? 
They don't cost nothing, since they still have to be lexed and parsed, but 
they don't get fully compiled.

You mean create other modules that get publicly imported by one module? I do 
think that sections of std.datetime would benefit from that.
