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.
