in reply to Re: my $1
in thread my $1

perl -e 'my $_ = 1' Can't use global $_ in "my" at -e line 1, near "my $_ "

That's just your copy of perl, which is too old :) Works fine in 5.10.

    ...ah, you're right, I had tried with 5.8.8.

    (/me wonders what that change is supposed to be good for... :)

    Baah, this gives me creeps.
    perl -e '@foo = map {$_=2; foo()} 1..10; sub foo{print}' 2222222222 $ perl -e '@foo = map {my $_=2; foo()} 1..10; sub foo{print}' 12345678910

    print "just another perl5.8 hacker"
      Baah, this gives me creeps.
      Does this give you also the creeps?
      $ perl -e 'for $x (1 .. 9) {$x = 2; foo ()} sub foo {print $x}' 222222222 $ perl -e 'for $x (1 .. 9) {my $x = 2; foo ()} sub foo {print $x}' 123456789
      Or is it the fact that Perl just got a little bit more regular that creeps you out?
