No. On the contrary, $main::var, as a package-level variable, will retain
its value and remain in the child.

Maybe there is yet a better way to handle it, but what I do is stock it in a
lexical variable in a subroutine:
sub x
{
my $x = ...
}
There was however a discussion on memory leaks in such cases, or did I miss
the final conclusion?
