Anyone seen a Javascript interpreter in Python?

btw, has anyone done an "pythonic syntax" javascript variant?  I look into 
having javascript without curly braces and ';'.  

I intend to implement *very small* conversion code both in javascript and 
python. Here is an example on how javascript would then look like:

def TransportDriver_http (parent):
	this.p = new XMLHttpRequest()
	this.parent = parent
	
	def load(filename, callback):
        var docu = document.implementation.createDocument("","",null)
        docu.loader = this.parent
		if (callback):
			docu.onload = callback
		else: 
			docu.onload = this.parent.xmlloaded
		docu.load(filename)
        return docu
	TransportDriver_http.prototype.load = load


def  translates to   function
:    translates to   {}ing the following indented block
\n   translates to   ;

There would probably only be a small user base but i would
be among them, i guess :-)  For me it's just to tiresome when 
switching often from python server code to client javascript code.

And for pythonistas it's still immediately recognizable as
javascript because of "this", "var" and other oddities :-)
