Matlab programmers, Java programmers, they all want D to act their way.

As for switch statements (and this is getting offtopic), there are
cases where fallback is nice to have..

final switch (param)
{
    case FILE_NEW:
    case FILE_OPEN:
    case FILE_SAVE:
    case FILE_SAVE_AS:
    case EDIT_UNDO:
        throw new Exception("unimplemented!");  // or there would be
one method that handles these cases
    case EDIT_CUT:
        handleCut();
        break;
    case EDIT_COPY:
        handleCopy();
        break;
    case EDIT_PASTE:
        handlePaste();
        break;
    case EDIT_CLEAR:
        handleClear();
        break;
}
return 0;

If you didn't have fallback, you would probably have to add some kind
of new statement like "goto next" or "fallback" on each of those
cases.

On the other hand, having to add break everywhere is a pain too. So
maybe the change would benefit overall.

The switch statement is a weird construct. It's as if suddenly you're
coding in Python with no curly braces. :)
