Optional argument types

[Aron Homberg]

Just to know the process better:
For such ideas, who is allowed to write a strawman-page in the wiki?

<noise>

Personally, I would like guards without that magic '::' syntax. Why
reinventing the wheel?
Just allowing/checking optional type's would be great:

var Number|Boolean|Null abc = null;
var String foo = 'bar';
var withoutType = 'yes';

function optType(HTMLElement|String domEl, withoutType='again') {
    // Nice lang :)
}

But this is only noise... :)
