yet one thing comes to mind as this switch /select (for smoe
reason select could be maybe a better word) could also work in
more ways than select variable and select value

it could also work like select value to watch in runtime, or select 
value to watch at acces - and it could be eventually good for
debig purposes like

int x = 20;

select4ac(x); //select for acces controll

case(<0) ERROR("");
case(x>639) ERROR("");
//throws errors if x would be set below 0 or above 639



it would burden the cpu dependant on use but its kinda interesting 
languege mechanism imo
