You don't understand: I *WANT* the code *FAIL* to compile because 
`S`'s constructor is `@system`. But instead, the `@system` 
constructor gets through because I had to use `@trusted` to get 
placement new itself to be considered safe. If I have to manually 
check constructor safety to get around this then I might as well 
just use `emplace`, which would make this a completely worthless 
feature.
