I haven't done this in any d programs, but in C++ programs, I used to use 
braces to create a scope in which to declare a variable.  What would happen 
here:

case x:
{
    int y = 2;
    ...
}
break;

I'm not super excited about there being such a subtle difference with the 
colon (if you automatically put a colon without thinking about it, then the 
break statement is required, meaning a very subtle bug), but other than 
that, I like the idea.  Why not make it more obvious?:

case (x, y, z) // similar to case x: case y: case z:
{
}
/* else case(a, b, c) ? */
