Maybe "simple and concise" takes a lot more work to extract from 
templates. I mean the type function version is so obvious it's 
probably what a newbie would write, the simple concise solution 
is the obvious one. Is the same true of the template / mixin 
versions?  Or do you have to be a D sage to make it palatable?
