Look at this
C:\>perl -MData::Dumper -MCGI -e"die Dumper( CGI->new( { 1..10 }) ) " $VAR1 = bless( { '.charset' => 'ISO-8859-1', '1' => [ 2 ], '3' => [ 4 ], 'escape' => 1, '5' => [ 6 ], '7' => [ 8 ], '.parameters' => [ '7', '9', '1', '3', '5' ], '9' => [ 10 ], '.fieldnames' => {} }, 'CGI' ); C:\>
Do all the keys map to one bucket? I'm pretty sure they don't.
C:\>perl -MData::Dumper -MCGI -e"warn Dumper( $a=CGI->new );die Dumper +(scalar $a->Vars() ) " a= b= c= d= e= f= g= $VAR1 = bless( { '.charset' => 'ISO-8859-1', 'a' => [ '' ], 'escape' => 1, 'b' => [ '' ], 'c' => [ '' ], 'd' => [ '' ], 'e' => [ '' ], 'f' => [ '' ], 'g' => [ '' ], '.parameters' => [ 'a', 'b', 'c', 'd', 'e', 'f', 'g' ], '.fieldnames' => {} }, 'CGI' ); $VAR1 = { 'a' => '', 'b' => '', 'c' => '', 'd' => '', 'e' => '', 'f' => '', 'g' => '' };
The only way all the various keys would map to one bucket would be when you construct a hash by calling Vars. Do you see what I'm saying, or did I miss something crucial.
update: I improved the 2nd snippet. Now it shows all the various keys going to a single bucket.

update: Why not just post the example?

perl -e "$q=$_;map({chr unpack qq;H*;,$_}split(q;;,q*H*));print;$q/$q;"
