I doubt that 'continue' can be used there - what if we have a caseof in a loop?

foreach(x; y)
{
    caseof(s[i])
    {
         case '': continue; // fallthrough or continue the loop?
    }
}

One could workaround this by giving the loop a label and using it
with 'continue', but still, this might be confusing for beginners.
