Title: Use inject instead of reduce.

Reduce is an alias for inject introduced in 1.8.7 -- using inject instead (while less readable) preserves 1.8.6 compatibility.

Now, I'm not sure how many people are *actually* using 1.8.6 and rspec 2 -- we do in CI, but only as a regression test for Jasmine. ;)
