How has support for dereferencing and postderef syntax changed across recent Perl versions?

Perl has evolved significantly in terms of support for dereferencing and postderef syntax in recent versions. Dereferencing allows you to access data stored in complex data structures, such as arrays and hashes, while postderef syntax provides a more straightforward and readable way to do this.

In earlier versions of Perl, dereferencing was often seen as cumbersome due to the need for additional syntax. However, with the introduction of postderef syntax in Perl 5.20, it has become easier and cleaner to manipulate reference data structures.

For example, in Perl 5.20 and later versions, you can access elements directly using the postderef syntax:

my $array_ref = [1, 2, 3]; my $value = $array_ref->[1]; # Easy access using postderef print $value; # Outputs: 2
