Re^2: About "state" variables in Perl 5.10

[citromatik]

Note also that with state each created anonymous sub gets its own copy of $x

Hmmm... but you can get the same result with the closure approach:

sub get_counter {
   my $x = 42;
   return sub {
      $x++;
   }
}
my $s = get_counter();
say &$s();

However, that difference is not why we introduced state variables. The big win is the psychological one of not having to look outside of the sub to find the definition of $x.

Nice, that reason convince me (and the one that kyle gave below).

Thanks
