I noticed several bugs in fusion::unpack_args (maybe one of them is rooted elsewhere) and wrote a small program that shows the problems:

Joao just fixed the CVS version. The file has been removed from the vault.
For the record... Tobias test case exposed some serious shortcomings in the implementation of unpack_args, which should now be fixed in CVS. They were: 1 - support for function pointers was completely broken. Specifically, I learned that result_of doesn't handle cv-qualified function pointers. 2 - Random Access Sequences were required when Forward Sequences would have been sufficient. Here I failed to grasp the Fusion Concepts while porting unpack_args from Fusion v1. 3 - Function references weren't handled at all. I also took the opportunity to rewrite and expand the test case, hopefully making it a bit more readable in the process... I'll take comments on that too ;-) Thanks for the report and the test case!
