Re: Variable scoping, foreach loop, alias

in reply to Variable scoping, foreach loop, alias

In your loop, $bla is being aliased to each element of the array in turn. So, when you modify $bla, you are really modifying the array element that $bla is referring to.

The same thing happens with $_ if you don't specify a variable. For example, try this as well:

my @arry = (1, 2, 3, 4);
++$_ for @arry;
print "$_\n" for @arry;
