Kat: In C/C++ and Java, case does this:

char all_ones(int exp)
{
   int result = 0;
  switch (a)
  {
     case 8: result += 128;
     case 7: result += 64
     case 6: result += 32;
     case 5: result += 16;
     case 4: result += 8;
     case 3: result += 4;
     case 2: result += 2;
     case 1: result += 1;
                 break;
     default; //Do nothing, result is zero
  }
  return result;
}

This function returns an 8-bit number that is all ones. (Yes, I know
it could be done with "return power(2,exp+1)-1", this is just an
example.)

It doesn't exit out of the switch statement until you call break. If
switch was implemented in Euphoria, I think it would have to do things
this way, as C/C++ and Java both do things like this, and most
programmers use one of the three languages.
