 as to this switch as i said the C jas some syntax that resembles switch and it is
 [2] { printf("one"), printf("two"), printf("three") }
 i mean it is like this compound sometheng you posted
   { printf("one"), printf("two"), printf("three") } [2]
   but with "key" on the left to ilustrate the analogy to
 swich(n) {case 0: printf("one"); case 1: printf("two"); case 2: rintf("three") }
 imo the resemblance gives to think
 the difference is this compound (array-like) example dont uses defined keys so it semms some should be added
 [n] {{1: printf("one")},{2: printf("two")},{3: printf("three")} }
 so those deduction on switch gives the above imo
 the question is if some things couldnt be ommitted for simplicity
 [key] {'A': printf("one"); 'B': printf("two"); 'C': printf("three"}; }

something like that
 (insted of
 switch(key)
{
case 'A': printf("one"); break;
case 'B': printf("two"); break;
case 'C': printf("three"}; break;
}

Here the switch looks clearer. Write it with 300 cases instead of 3, then that becomes obvious.
The first time I wrote a big C program, I used a syntax like this:
   switch (x)
   when 'A', 'B' then printf("one")
   when 'C'      then printf("two")
   else               printf("three")
   endsw
This needed to be converted to normal C before compiling, but the macro system wasn't quite up to the job (making using gnu C which allows for lists of case labels).
Instead I used a script to do the conversion, which needed 1:1 line correspondence. The result was something like this:
   switch (x) {
   break; case 'A': case 'B': printf("one");
   break; case 'C': printf("two");
   break; default:  printf("three");
   }
