No more fall through in case statement?

I'm sure you know this already, but: "Warnings are not a defined part
of the D Programming Language."

Either it's an error, or it's not.

Hey - here's an idea. Why not make case statements have a syntax
similar to D's attributes. That is, if you use a colon, execution
continutes to end of scope (or break), but if you use curly braces,
only the stuff within the braces gets executed. (Just like "public",
"private", etc.)

For example:

    case 1:
        /*...*/
        /* falls through */
    case 2:
        /*...*/
       break;
    case 3
    {
        /*...*/
    }
        /* does not fall through */

Existing syntax will still work, so that C++ programmers won't get
confused. To get no-fall-through behaviour, you'd have to replace the
colon with an opening curly brace (and remember the closing brace).
Everyone's happy. (Maybe?)
