Thanks a lot for the patch!

I think we can do a little bit better in this case: The archive contains 
the function's number of parameters - after all the parameters are 
stored in it. So, let's use this information and try a little harder 
matching the correct overload when reading the archive node.

I've committed a fix.

PS: Vladimir, I can't believe that you don't know what zeta is.  :)
