great to see you thinking about this important topic so early in your programming career!

Haha! Thanks eyepopslikeamosquito

I suppose the second part of the original question was the more significant part for me...is there ever a case in the current day to write a module that isn't OOP. The discussion has certainly answered that there is.

To keep writing style consistent across our company, we use a style guide which, among other things, sets a minimum Flesch Kincaid Grade Score. We mostly use Hemingway to check our copy. However, we have internal editors for blogs, emails, etc. so I thought it would be helpful to have a real time Grade Score on these. To that end, I found an existing Javascript Flesch Kincaid module. I wanted Javascript to avoid lots of AJAX calls.

To my surprise, I found that the Grade Score from this was vastly different from Hemingway for the same piece of text. I was surprised because Flesch Kincaid is a well-defined mathematical formula. After some investigation, it seems the difference comes from the difficulties in programatically counting syllables.

So I thought I'd write my own module to obtain a Grade Score. I know there are Text::Info and Lingua::EN::Fathom. The latter I am using to create a copy checker that also includes a ratio of first person to second person pronouns. Both these modules count syllables using Lingua::EN::Syllable which the author notes is not entirely accurate although this is not especially important for my application.

Far more important to me is consistency. I need a Perl module and a Javascript module that function the same way and obtain the same result for a given block of text...any block of text over a dozen or so words. Hence looking at writing my own. That way I can create the syllable counting regexp in Javascript and Perl in a way that should produce consistent results in both languages.

My instincts tell me that this is best not done using an OOP module. But I couldn't explain why. Now, given the helpful and informative discussing, I understand some of why my instincts were right. I guess my judgement was also clouded by having only written OOP modules recently. I also think that the choice was mostly right for those too.
