I just think I've gone a bit too far

My experience is that if you "think you've gone a bit too far" you know you've really gone way too far. Split your code up so that each line saves it's results into an array, and use that in the next step.

Doing that will make the code

• self documenting (as long as you use sensible variable names)
• easier to read
• easier to test
• easier to debug
• easier to understand
• easier to change

(And I'm as guilty as anyone else for making single statements too long and too complex)
