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;
