The important question to ask is "why am I making this thing an object?"

Recently I ripped apart a CGI script that I wrote - one script handled 3 different pages, so I decided to decompose it. In the process, there were many subroutines that needed to be shared - should I create an object or should I create a module? I created both.

I placed he common functions (stripping out leading and trailing whitespace, SQL queries, etc.) into a module and created an object to store errors that were generated from bad user input (such as blank fields, letters instead of digits, etc.). Some things are objects, others are just patches of functions quilted together.

I might use that error object in another CGI application, but I doubt I will use the module, it is too specific and not general enough. It's easier for me to cut and paste the white space stripping function I wrote, or better yet, copy the module and delete the stuff I don't want.

But I ain't touching the inards of my error object until I absolutely have to, they'll have ta pry it from my cold, dead hands. . .
