hasAttribute in Web.DOM.Element fails

[IfSixWasNine]

The cause is that the return type has not an effectful implementation.

Instead of ...
exports.hasAttribute = function(name) {
return function (element) {
return element.hasAttribute(name);
};
};

... the implementation should be ...
exports.hasAttribute = function(name) {
return function (element) {
return function () {
return element.hasAttribute(name);
};
};
};

Thanks for the report!
