Will macros work with expressions?

[Bill Baxter]

A question about the upcoming macros:
Will they work for expressions as well as statements?

The examples in WalterAndrei.pdf all show complete statements,
like
    macro foo(e) { e=3; }

But will it be possible to have:
    macro foo(e) { e+3 }

I hope expressions will be allowed.  Not for things like e+3 but for 
making local shortcuts where aliases don't cut it:

    macro call_func( arg ) {
       $this.some_member.a_really_long_named_template_member(arg);
    }
    ...
    writefln(call_func(1));
    writefln(call_func("hi"));

And I'm sure there'd be any number of other uses for expression macros.
