This discussion let me think a thing that, one of my co-workers, who is good at
both C and perl programming. When coding with Perl, he always like to put a
'return 0' on the end of each subroutines (maybe learn the habit from C?). So
for his packages, the methods which were executed successfully will return 0. I
think this behavior will make confuse for another perl caller. Is this not good
prac on Perl style?
