Your good reason has a corollary, which happens to be another good reason to use the original code. This modifies the original array:

@array = 1 .. 10; for my $var (@array) { $var++; print "$var\n"; } print "@array\n";

But this does not:

@array = 1 .. 10; for (@array) { my $var = $_; $var++; print "$var\n"; } print "@array\n";
