Perl pragma to disable multidimensional array emulation
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. To enable it, simply say . no multidimensional; . at the beginning of your script.
