my fisrt japh with the unpack function
While I don't want to discourage your efforts in extending your knowledge of Perl and the functions therein, I must object to this being classified as "obfuscated code". The primary reason for this is that the code logic and execution is hardly obscured or hidden - It is a single unpack statement from which the results are print-ed, nothing more.
For a bit of background reading on how to write really good obfuscated code, I would recommend having a look at the two obfuscation code reviews by japhy here and here. Also too have a look at the obfuscated code written by the mighty Erudil, including the camel code.
Ooohhh, Rob no beer function well without!
