Thank you for the reply. I don't want to set maximum length on a hex string. I work with very big numbers so hex() is out of question, and in my case byte string is actually what I want to get.
The map/for is quite interesting, however I was hoping there's a clever way to work with parameters in pack() itself, which would change it's behavior to pad left side (I couldn't find anything like that on my own).
Inserting a tiny function like this seems to be the best solution, however as this is meant to be in a CPAN package I wanted to keep it as clean as possible, and at least two of my files will require this functionality. Why do it even pad numbers on the right side?
