...and *this* is where, in the long long history of this thread, where I finally realized the *real* issue here.

Let's take Rails... rails, activerecord, activeresource, actionpack, actionmailer, and activesupport...

106,518 lines of Ruby code

66 instances of foo += 1 (or foo += 100)

That's 0.06% of the lines of code! If you're writing Ruby code and your fraction is higher, chances are you're "doing it wrong".

Cheers,
