Yes, good points. except for the 'can' thing. I usually assume (especially for a tutorial) that nobody is trying to fool me. If someone did repplace can(), he must know what he's doing.

I'll fix the explanation about require. 

perl -e'$b=unpack"b*",pack"H*","59dfce2d6b1664d3b26cd9969503";\
for(;$a<length$b;$a+=9){print+pack"b8",substr$b,$a,8;}'
