they added `if constexpr` not `static if`, which is another thing 
to add to the list of worst features implemented. The critical 
difference is that `if constexpr` always adds a scope whereas 
`static if` doesn't. Adding a scope if you need it costs you {}. 
This prevents `if constexpr` from being able to conditionally 
declare declarations (variables, members, members functions etc.)
