Uhhhhh, after I have read the Object Oriented Perl book, I wish that there is some UML modeler that will let me customize the perl OO code generation.. huhu anyway, my evil perl code is hard to read whether I use the normal or OO style coding, for me, I will need some modeler + good source code documentation + good OO design skill along with the OO Perl skill.. all together to ease my perl life :)) Studying/Exploring/Developing/Finding those tools might be the next step that will highlight the usefulness of studying OO Perl. In the opposite way, if I can find a good perl development tools that will help me with the source code documentation, it may drag my interesting away from OO Perl (e.g like having Siemen 's EasyCODE for Perl.hu hu) Infer: knowing OO Perl is not the last thing that I have to study for my perl life :D *uh, what if LabVIEW or IFAD VDM++ can generate OO Perl code!*
