Says who? Perl understands scopes perfectly well.
sub foo {
die q<why doesn't this show up?>;
}
sub bar {
my $x;
open my $h, '>', \$x;
local *STDERR = $h;
foo();
}
bar();
At runtime:
1 main calls bar()
2 bar() sets stderr alias to last until bar's scope is over.
3 bar calls foo()
4 foo() calls die()
5 die() writes to stderr
The bar() scope set up at 2 is *clearly* still extant at
stage 5. Notice the indentation. There is no question
that Perl is behaving per design and documentation.
It may not be doing what *you* expect it to, but that is
an entirely separate matter.
