-a only works in combination with -n or -tI assume this is a typo and Abigail meant -n or -p. Actually, even without -n or -p, the -a switch does have the very minor effect of creating @F, so that referring to it won't get you a Name "main::F" used only once: possible typo warning. (And *F{ARRAY} will give a reference to @F even if no @F is mentioned anywhere, instead of the usual undef.) These could be construed as a bug.
