Re: hashes over easy

Hi Uri:  I enjoyed reading through your slides.

I think I caught a typo, though:

On the 'Is A' slide, the example is:

my @foos = qw( foo bar baz ) ;
my %is_a_foo = map { $_ => 1 } @foos ;

if( $is_a_foo( $key ) {
 	...
}

Shouldn't this be:

if( $is_a_foo{$key} ) {
...
}

Regards,
