Yes, later lines with the same key would overwrite any previous value
for that key, that's how hashes work.
In your initial mail you didn't mention that there are duplicate keys.
What is it you want to achieve? Store an arrayref of potentially
multiple values for each key?
If so, for each key & value pair you could say something like:
push @{ $hash{$key} }, $value;
Then later, e.g.:
say "Values for 22:5a are: " . join ',', @{ $hash{'22:5a'} };
Is that what you're looking for?
