I often find myself writing code that looks like this:

void blah (Object x)
{
    if (x instanceof ClassOne)
    {
        ClassOne x1 = (ClassOne) x;
        ...;
    }
    else if (x instanceof ClassTwo)
    {
        ClassTwo x2 = (ClassTwo) x;
        ...;
    }
    ...;
}

It'd sure be nice if Java offered a typecase-like statement,
especially since it already has it for exceptions! The above could
look something like this:

void blah (Object x)
{
    typeswitch (x)
    {
        case ClassOne x1:
        {
            ...;
            break;
        }
        case ClassTwo x2:
        {
            ...;
            break;
        }
        ...;
    }
}
