如何在ADVANCED_OPTIMIZATIONS中的Closure Compiler中导出公共类方法？

Question

I'm using JavaScript inheritance inspired by John Resig and my library code looks like the following:

var Person = Class.extend({
  /** @private */
  _dancing: null,

  /** @private */
  _init: function(isDancing){
    this._dancing = isDancing;
  },

  /** @public */ 
  dance: function(){
    return this._dancing;
  }
});

var obj = new Person();
obj.dance();

What's the best way to mangle only those class methods that starts with underscore and save all public methods in ADVANCED_OPTIMIZATIONS.

I need to get the following output:

var a = Class.extend({a:null, b:function(b) {
  this.a = b;
}, dance:function() {
  return this.a;
}});
new a;
a.dance();

The "easiest" way to do this would be to create a custom coding convention for the compiler (you have to modify the compiler) and change the "export" convention to be anything not starting with "_".

See:

http://closure-compiler.googlecode.com/svn/trunk/src/com/google/javascript/jscomp/GoogleCodingConvention.java

and its "isExported" method.
