in thread Why Would HTML::LinkExtor return a hash of attributes?

Isn't it a hash?

Why does it have "key => val, key => val" if it isn't?

Plus, if it isn't, why does the sub grab it as: 

  my($tag, %links) = @_;

if it isn't a hash?

 all that sub needs to be is print "@_\n" Try it. You get both the "HREF" and the thing it's a link to. I don't want to extract "HREF" 5,000 times do I?

     => Is a fancy comma (,). It allows you to say 
    print I => AM => NOT => QUOTING => WORDS => TIMES => 5;

    which would print IAMNOTQUOTINGWORDSTIMES5

    Using this fancy comma doesn't make a hash. A hash is a "data structure", and I => AM => NOT => QUOTING => WORDS => TIMES => 5 is a list.

    Now you can do many things with lists. You can create arrays ( also data structures ) 

    my @ARRAY = ( I => AM => NOT => QUOTING => WORDS => TIMES => 5 );

    and you can create hashes 
    my %HASH = ( I => AM => NOT => QUOTING => WORDS => TIMES => 5 );

    . Do you follow now?
