NAME ^

multidimensional - disables multidimensional array emulation

VERSION ^

version 0.011

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;
