In order to support fields of the same name in subclasses we are now prefixing them with name of the class that defines them. To provide convenient way to access them from generated bytecode and also directly from JavaScript, there is a getter/setter function for each field. It starts with _ followed by the field name. If called with a parameter, it sets the field, with a parameter it just returns it.

29 * The <code>Runnable</code> interface should be implemented by any
30 * class whose instances are intended to be executed by a thread. The
31 * class must define a method of no arguments called <code>run</code>.
33 * This interface is designed to provide a common protocol for objects that
34 * wish to execute code while they are active. For example,
35 * <code>Runnable</code> is implemented by class <code>Thread</code>.
36 * Being active simply means that a thread has been started and has not
39 * In addition, <code>Runnable</code> provides the means for a class to be
40 * active while not subclassing <code>Thread</code>. A class that implements
41 * <code>Runnable</code> can run without subclassing <code>Thread</code>
42 * by instantiating a <code>Thread</code> instance and passing itself in
43 * as the target. In most cases, the <code>Runnable</code> interface should
44 * be used if you are only planning to override the <code>run()</code>
45 * method and no other <code>Thread</code> methods.
46 * This is important because classes should not be subclassed
47 * unless the programmer intends on modifying or enhancing the fundamental
48 * behavior of the class.
