NAME
       multidimensional - disables multidmensional array emulation

VERSION
       version 0.010

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 multidmensional 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.
