You're right, that does work. However, the reason I was using \@ in my prototype was so that I could modify the list. Copying into and then dereferencing a new list defeats the purpose. What I have ended up doing is using a prototype like this 
sub subby(&\@@)

Then, I can modify the first list (but only pass it in as @list) and for the second list, I can use grep and friends to produce it, which suits my needs. Thanks
