Empirically, the documentation seems to be a little inaccurate as the fat comma also seems to work if the word on the left starts with a number and consists only of numbers.

$ perl -Mstrict -Mwarnings -MData::Dumper -E '
> my %hash = (
>    1  => q{one},
>    11 => q{eleven}
>    );
> print Data::Dumper->Dumpxs( [ \ %hash ], [ qw{ *hash } ] );'
%hash = (
          '11' => 'eleven',
          '1' => 'one'
        );
$
$ perl -Mstrict -Mwarnings -MData::Dumper -E '
> my %hash = (
>    1  => q{one},
>    11 => q{eleven},
>    2t => q{fruity},
>    );
> print Data::Dumper->Dumpxs( [ \ %hash ], [ qw{ *hash } ] );'
syntax error at -e line 5, near "2t"
Execution of -e aborted due to compilation errors.

I hope this is of interest.
