The top level static assert has no value.

I went through with this let-the-user-pick thing in simpledisplay 
too, like described in the blog. It was a bunch of work that led 
nowhere; it is better to just leave the identifier undefined and 
let the test process catch it.

These things look like a good idea when you're starting a new 
project, but they don't stand up to experience supporting things 
long term.

hahaha another example of how D's `version` keyword is useless 
baggage in the language, even for this trivial thing, you'd 
rather have an `enum`.
