The "bareword" may also start with a "-".

    It seems to treat as an octal number, converts to decimal and then stringifies by the look of it.

    $ perl -Mstrict -Mwarnings -MData::Dumper -E ' > my %hash = ( > 011 => q{nine}, > 11 => q{eleven}, > _2t => q{fruity}, > ); > print Data::Dumper->Dumpxs( [ \ %hash ], [ qw{ *hash } ] );' %hash = ( '11' => 'eleven', '_2t' => 'fruity', '9' => 'nine' ); $ $ perl -Mstrict -Mwarnings -MData::Dumper -E ' > my %hash = ( > 08 => q{eight}, > 11 => q{eleven}, > _2t => q{fruity}, > ); > print Data::Dumper->Dumpxs( [ \ %hash ], [ qw{ *hash } ] );' Illegal octal digit '8' at -e line 3, at end of line Execution of -e aborted due to compilation errors. $

    A zero on its own is fine.

    Update: I'm an idiot, I meant to post as a reply to this :-(

    Cheers,
