No. Keep in mind, this is Perl, not C. Perl does what you need, not
what was easiest to implement.
The reason is ... my() variables are not alocated on stack, but on
heap. Therefore they do not have to be destroyed when you leave the
function, but, just like all other values, live as long as there is a
reference to them.

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
