Hi,

To delete a key, you don't need to know her value.
Here's my code :

my %hash = ( Carol => 22, Mary => 21, Chris => 30 );
map { delete $hash{$_} } keys %hash;

Update: Of course this makes use of map in void context. Yick. And a couple other suggestions came in by way of followup:

• delete @hash{(keys %hash)}; # Hash slice
• %hash = (); # Most efficient method.
