FAQ
This is a bug report for perl from "Anton Tagunov" <tagunov@motor.ru>,
generated with the help of perlbug 1.33 running under perl v5.7.3.


-----------------------------------------------------------------
Hello!

1) Both of the following examples print their source :-(

use strict; use warnings;
open FH, $0 || die "$!";
open GH, "<&=FH";
close GH;
while(<FH>){print}

use strict; use warnings;
open FH, $0 || die "$!";
open GH, "<&=FH";
close FH;
while(<GH>){print}

That is <&= behaves like <&.

2) BTW, open FH, '-' behaves neither
like '<&=STDIN' nor like '<=' should behave:

open STDIN,'<'.$0;
open V,'-';
close V;
while(<STDIN>){print}; #prints the source

open STDIN,'<'.$0;
open V,'-';
close STDIN;
while(<V>){print}; #does not

3) Is this it like expected? Is it documented
anywhere? Where should this be documented
if it is not documented?

4) I have found no tests for this. Are there any?


Regards, Anton
