creating an reference to an anonymous hash from ARGV 1

[ianfo]

Hi,

Does anyone know the easiest way to create a reference to an anonymous hash using the values in ARGV to populate the keys for the hash?

for example. if my program was called like this

./prog A B C D

How would I then create a ref to an anonymous hash with keys A B C D (but with no associated values at this point)

Hope i've worded that correctly!

$anon_hash_ref = {};

$anon_hash_ref->{$_} = "" for (@ARGV);

Hope that helps.
