You are free to disregard that knowledge and experience. But I think that in so doing you've missed a valuable learning opportunity. I apparently wasted my time in trying to educate you about fundamental software development concepts that let you see the larger picture.

It is obvious how convenient it is to type one line less now. You see that and think your modules are wonderful. It is much less obvious that they will lead to longer debugging sessions 3 months down the road. It is very far from obvious that we spend more time and energy debugging code than we do developing it, so it pays off in the long run to focus on coding in ways that avoids creating problems that need to be debugged, and ones which will make debugging faster when you have to do it.

Someday you may learn that lesson. But obviously that won't be today.

For what it's worth, tilly, at least I learnt something today, so your time was not wasted.

Thanks.
