but the question is the details, like mentioned

such free form is somewhat low lewel than the normal
switch case imo..it also has no break but what it could
be seem if swich selects by value then probably break
is not needed as the other cases could be optimised
away (though  maybe not fully..) if switch is by variable
then maybe less

overally this switch is a mess but it seem to me that this kind
of free form  is better that the swich in c (though im not fully sure also)
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
