And if you find yourself using the static method qx.lang.Function.bind(...)
a lot and would prefer to be able to just say this.bind(...) you use this
code in your applicaiton:
// Add a bindTo() method to qx.core.Object as a shortcut to constantly
// having to use qx.lang.Function.bind()
qx.Class.include(qx.core.Object, custom.MObject);
Here's the actual mixin to add to your project:
