multidimensional(3)

NAME
multidimensional - disables multidimensional array emulation

VERSION
version 0.014

SYNOPSIS
    no multidimensional;

    $hash{1, 2};                # dies
    $hash{join($;, 1, 2)};      # doesn't die

DESCRIPTION
Perl's multidimensional array emulation stems from the days before the language had references, but these days it mostly serves to bite you when you typo a hash slice by using the "$" sigil instead of "@".

This module lexically makes using multidimensional array emulation a fatal error at compile time.

METHODS

  unimport
Disables multidimensional array emulation for the remainder of the scope being compiled.

  import
Enables multidimensional array emulation for the remainder of the scope being compiled;
