That is, lexical variables that don't share a scope are unreachable.
Not strictly true since you can modify lexical variables with the help of PadWalker. Here's some code from the docs 
sub increment_my_x {
    my $h = peek_my (1);
    ${$h->{'$x'}}++;
}

my $x=5;
increment_my_x;
print $x;  # prints 6

Although you'd have to be quite a disturbed individual to use this sort of thing in production any code ;-)
