It's an interesting situation that you've found. The foreach is a static 
foreach, so it gets unrolled at compile time. In each unrolled bit, 
'member' is a compile-time constant, so the if statement becomes either 
true or false. The code is in fact unreachable in that iteration.
So the warning is correct, but arguably not helpful.

Maybe we should suppress unreachable code warnings inside unrolled code.
