this works basically, thanks, but it has some limitations:

I can call the new method now with Math.cos, but: If an other script  
includes Math, then not the modified proxy class will be included but the  
original module, so I loose all the new stuff :( This is bad because I  
dont really want to rewrite the other scripts.

Second, a minor issue compared to the first, is that I have to watch not  
to load my code twice, otherwise I overwrite my alias and the original cos  
is lost..

I try hard to figure out how to make it better, but it seems that I'm  
stuck..

bye!
