The point with #inject was to be faithful to Smalltalk, which uses that
name. Again, I am sorry for having recommended #inject.

In GridFlow (my biggest Ruby library), that thing is called #fold. I guess
I must have taken the name from Haskell. To me it's more
meaningful-sounding than reduce, but your mileage may vary.
