.SH DESCRIPTION
.IX Header "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 \f(CW\*(C`$\*(C'\fR sigil instead of \f(CW\*(C`@\*(C'\fR.
.PP
This module lexically makes using multidimensional array emulation a
fatal error at compile time.
.SH METHODS

.IX Subsection "unimport"
