NAME
       Perl::Critic::Policy::Community::MultidimensionalArrayEmulation - Don't use
       multidimensional array emulation


DESCRIPTION
       When used with the "@" or "%" sigils, a list in a hash subscript ("{}") will access
       multiple elements of the hash as a slice. With the "$" sigil however, it accesses the
       single element at the key defined by joining the list with the subscript separator $;.
       This feature is known as "Multi-dimensional array emulation" in perldata and provided a
       way to emulate a multidimensional structure before Perl 5 introduced references. Perl now
       supports true multidimensional structures, so this feature is now unnecessary in most
       cases.

         $foo{$x,$y,$z}   # not ok
         $foo{qw(a b c)}  # not ok
         $foo{$x}{$y}{$z} # ok
         @foo{$x,$y,$z}   # ok
