I suppose what you really want/need is to pass the hash as reference, like this you don't need to pass the values and the keys separately.

 call(\%hash)

If you explicitly want to pass the reference of a copy do this

 call( { %hash } )

the { ... } returns a ref of an anonymous hash of the list expanded from %hash, i.e. the ref of a hashcopy!
