opDispatch rox, and there's all kinds of crazy stuff you can do
with it. In my dom.d, I used it for three things:
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/dom.d
1) easy access to attributes (node.href = "dlang.org"; and auto
href = node.href;) using the technique you just showed.
2) the style stuff, which does a little rewriting:
node.style.marginLeft = "10px"; -> adds "margin-left: 10px;" to
the style attribute
3) Forwarding collections:
document[".cool"].addClass("cool2");
uses opDispatch to forward any method to the collection without
me writing much boilerplate code.
This is also nice for calling external dynamic apis, you can use
opDispatch to forward over a network call or something like that.
I also used it in my jsvar.d file to make a var type in D, very
similar to in Javascript:
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/jsvar.d
var a = var.emptyObject;
a.cool = { writeln("hello world!"); }
a.cool()(); // double parens needed due to broken @property
a.bar = 10;
writeln(a.bar); // works
and so on. D rox so much.
