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;
