Hi,
I use to create hash references for using them as config files like:
{
first_item => '...',
second_item => '...',
third_item => '...',
#...
};
Sometimes the hash gets bigger and I can add a new item in the hash that
already exists.
I know that if there are more keys with the same name, the last is used, but
I would like to clean the hash. Is it possible to find out the dupplicate
keys?
Thanks.
Teddy
