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; SEE ALSO "$;" in perlvar, B::Hooks::OP::Check.
