issue with privatize fails with Better.Function

[jeromeetienne]

Bogus case

    var Foobar  = Better.Class(function(){
        this._steps     = [];
    }, {
            // arguments: [],
            privatize: true
    })

    Foobar.prototype.push = Better.Function(function(arg){
             this._steps.push(arg)
    }, {
            arguments: ["String"],
            return: undefined
    })

    // ---------------------------------------------

    var foobar = new Foobar();
    foobar.push("test");

Explaination

• when the _steps is accessed, the caller is compared to the list of private function
• but the private function is the Better.Function one... so the comparison fails
• if the .push is declared as a normal function, not Better.Function, we compare the good function

Solutions

• if the function is a BetterFunction, stack the original function, and not the better function
