That's the Frog specific implementation.

 
 // Wrap a 0-arg dom-callback to bind it with the current isolate:
 function $wrap_call$0(fn) { return fn && fn.wrap$call$0(); }
 
 Function.prototype.wrap$call$0 = function() {
   var isolateContext = $globalState.currentContext;
   var self = this;
   this.wrap$0 = function() {
     isolateContext.eval(self);
     $globalState.topEventLoop.run();
   };
   this.wrap$call$0 = function() { return this.wrap$0; };
   return this.wrap$0;
 };
 
 // Wrap a 1-arg dom-callback to bind it with the current isolate:
 function $wrap_call$1(fn) { return fn && fn.wrap$call$1(); }
 
 Function.prototype.wrap$call$1 = function() {
   var isolateContext = $globalState.currentContext;
   var self = this;
   this.wrap$1 = function(arg) {
     isolateContext.eval(function() { self(arg); });
     $globalState.topEventLoop.run();
   };
   this.wrap$call$1 = function() { return this.wrap$1; };
   return this.wrap$1;
 };
