Hi!

I found out - :-( - that if you write a code like: 

my @a = (1 .. 9);  # for instance!!
for my $e (@a) {
  $e += 1;
}

[download]

you REALLY!! change the array element represented by $e.

So, to modify a copy you have to write: 

my @a = (1 .. 9);  # for instance!!
for my $e (@a) {
  my $ee = $e  # copy current element
  $ee += 1;
}

[download]

Can anyone tell me if exists a shorter way or quicker solution to obtain what I want (i.e. to modify an array element) ?
