The with statement is one where I think it would be interesting to
make it an expression.

For named parameters (admittedly, I find this one a bit ugly):
foo(with(ParameterTypeTuple!foo) {
    abc = 2,
    def = 3
});

Or just:
auto args = with(ParameterTypeTuple!foo) {
    abc = 2,
    def = 3
};
foo(args);


For initialization:
auto a = with(new FooBar()) {
    name = "Foo",
    bar = 3
};

Or:
with(new Thread(&foo) {
    isDaemon = true
}).start();

Sadly it'll break all the code that currently use it, since we'll now
need to terminate it with a semicolon.

Well, no. That does not follow. We can have both a with statement and a 
with expression.
