Function with optional arguments

[kevinresol]

class Main{
    static function main() {
        var f:(value:String, ?event:Int)->Void = null;
        coconut.Ui.hxx('<Foo f=${f}/>');
    }
}

class Foo extends coconut.vdom.View {
    @:attr var f:(value:String, ?event:Int)->Void;
    function render() return null;
}

src/Main.hx:4: characters 20-23 : error: Optional attribute of parameter  differs
src/Main.hx:4: characters 20-23 :  have: { f: coconut.data.Value<(..., Dynamic) -> ...> }
src/Main.hx:4: characters 20-23 :  want: { f: coconut.data.Value<(..., Dynamic) -> ...> }
src/Main.hx:4: characters 20-23 : For function argument 'attributes'

There are a few quirks here:

• why Dynamic?
• why mis-match optionality?

Tried to print getExpectedType for the attr:

TFun([{name: , t: TInst(String,[]), opt: false},{name: , t: TAbstract(Null,[TAbstract(<...>,<...>)]), opt: false}],TAbstract(Void,[]))

so the second arg is Null<Int> but opt:false
