I like it. a few questions:

Would it only work with literals? what about nested functions?

I have always thought that delegates should be able to be scope on anything 
you want:

struct Foo { int bar; }

Foo* f = new Foo;
f.bar = 0;

auto inc = f.new { this.bar++; }

inc();
assert (f.bar==1);


or even:

int i = 5;
auto times = i.new (int j){return this*j;}
i=6;
assert(times(i) == 30);
