and always has as far as I know, so please share your hallucinogens
with the list:)
Sadly, the hallucinogens are essential, not external. But I'm pretty

I misremembered the reason for the construct, though: assigning to
undef has always been ok (even in perl4 and probably earlier), but
declaring "my undef" wasn't, iirc.
