in reply to Misunderstanding dereferencing

Some old discussion on the same topic. Looks like it's a well-known bug that everyone is too scared to fix :-)

As meryln says in that thread:

an array name is sometimes automatically a reference to that array, even though the language definition would argue otherwise

    Looks like its been fixed in bleed: 
    $ cat /tmp/p
#!/usr/bin/perl

@a = qw(1 2 3);
@b = qw(a b c d);

push @{ $x ? @a : @b }, 'foo';

print "a: @a\n";
print "b: @b\n";
print "3: @3\n";
print "4: @4\n";
__END__

$ ./perl /tmp/p
a: 1 2 3
b: a b c d
3: 
4: foo

      I see no error so I'm wondering what is the behaviour now. Does it push 'foo' to the array @4 (@b evaluated in scalar context) ?

      Edit: sorry I didn't read to the bottom of your code...

      Edit2: more sincerity

    Thank you. Glad to know I wasn't being a total idiot in getting confused on that one.

    Cheers,
