# multidimensional(3pm)

disables multidimensional array emulation

## NAME

multidimensional - disables multidimensional array emulation

## VERSION

version 0.014

## 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 multidimensional array emulation a fatal error at compile time.

## METHODS

### unimport

Disables multidimensional array emulation for the remainder of the scope being compiled.

### import
