The difficulty is, that my assumptions were broken. And even with irb,
the assumptions *I* make aren't checked. Neither would unit tests or
similar things: If my assumptions are incorrect, and I don't know it,
I'll write tests and code that validate my assumptions.

The difficulty, if one is working alone, to find a way to check
assumptions (and looking up the math formula for calculating the
Euclidean distance between two points helped my catch another assumption
I made, fortunately), which co-workers or so could provide.

Ah, well, this just shows that I have to check my assumptions, too, and
perform due diligence when working on something. Which is blatantly
obvious, of course, but I needed that reminder, obviously.

I'm just glad that I only write code in a vacuum, but don't exist in one. :P
