Nice, another little trick I didn't know. That shift defaults to working on @ARGV in certain cases, I always would have assumed @_ had I not been confused at first seeing you do this choroba.

shift

Shifts the first value of the array off and returns it, shortening the array by 1 and moving everything down. If there are no elements in the array, returns the undefined value. If ARRAY is omitted, shifts the @_ array within the lexical scope of subroutines and formats, and the @ARGV array outside a subroutine and also within the lexical scopes established by the eval STRING , BEGIN {} , INIT {} , CHECK {} , UNITCHECK {} , and END {} constructs.
