AFIK, you can't reference to core functions because there are build-ins, i.e. written in C, and not normal Perl functions. The only way to pass them around is to enclose them in an (anonymous) subfunction like shown by tye above. In general you should know that most build-in functions are using prototypes, e.g. pop awaits an array as first argument. So you would have to rebuild this prototypes in your subfunction to get the same usage syntax. I'm not sure if you can use prototypes with anonymous subfunctions, but you could still create a named one and reference it.
