Well, this is a bike shed argument. I find using "shift;" instead of
"shift(@_);" when inside subroutines to be faster to write, more concise and
more idiomatic. shift has this magic for a reason. I'm unlikely to use shift
the other way when outside or inside subroutines. (And if I do, my automated
tests will catch this.)
