Programming Style Original Idea

• We can use polymorphism in perl. Use it and object composition instaed of multiple inheritence.

• Perl 5's OOP is not OOP. Do not depent on it. It just provides simple use of variable since variable itself knows the home (object / package).

• Interface for re-use and abstraction should be OOP style.

• We want to use OOP style in using Perl 5 but take care for OOP-ism. Balance is important.

• not use deep inheritence.

Programs in libexec/ describes the basic flow of processes. They may be allowd to be structured not object oriented programming

Polymorphism and re-use is important especially in sub-classes.
