How has support for array slices changed across recent Perl versions?

Support for array slices in Perl has evolved through recent versions, bringing new features and improvements that enhance the way developers work with arrays. Here are some notable changes across recent Perl versions:

  • Perl 5.20: Introduced the ability to use array slices as the left side of a list assignment, allowing for more streamlined code.
  • Perl 5.22: Added support for slicing multidimensional arrays, making it easier to manipulate nested data structures.
  • Perl 5.26: Enhanced error messages for improper slice operations, helping developers debug their code more effectively.

Here’s an example of using array slices in Perl:

# Define an array my @array = (1, 2, 3, 4, 5, 6); # Use an array slice to get a portion of the array my @slice = @array[1..3]; # @slice now contains (2, 3, 4) print "@slice\n"; # Output: 2 3 4
