thanks for the support

I am wondering about the performance loss if you do this with the 
current handles and store the counter in the callsite object. I mean 
with foldArguments and a void method you can make such an counter I think.

How would such support look like? A lookup with classes and the API 
matches that not exactly, but whatever is callable by Java rules?
