The alternative to your InsertMultipleValues() could have been a barebones sub that did only what you needed it to at the time of writing. Worse yet, it could have done so poorly.
I have the unfortunate task of working on a lot of code that uses Bad Programming, and cuts every corner possible. In the nine months I have spent with my current company, 90% of my time has been spent fixing or extending bad code.
Enters stage-left: Management
To make matters worse, when tasked with a new addition to the multitude of systems, I block out code and submit a proposal to my barely-technically-adept PHB.
"But that's not in the specs for what we need right now! There's no reason to make this a module, just tack it into the end of program XYZ. We do have to pay you for this time you spend, you know!", he'll spout.
I'm left to make my successors' lives equally as miserable as mine has been.
*Shrug* ... But what do I know, I'm "just a programmer". He (project manager) has more Industry Experience.
Updates: fixed some minor end-of-the-week-tired-and-i-want-to-go-home, grammar, and tag errors. =)
