This is another case where I can kinda get it in isolation, but 
it is weird coming together with everything else. The propagation 
of size through the expression... but it is a bit weird that 
explicitly slicing it *still* prefers the static size version.... 
but ONLY when the compiler can prove the size. Break it into two 
expressions, and you get the other overload again.

The rules make sense alone, but together, they are just bizarre.
