#injecting on Enumerable
Reported by Adam Keys | September 3rd, 2008 @ 11:24 AM | in 2.x
injecting makes inject easier to use.
Rather than returning the accumulator from your block, the
accumulator is modified in place.
Apparently Merb had this method for a while, but lost it in the rewrite. I've adapted it to Rails in an idiomatic style.
For example:
%w(foo bar).injecting({}) { |hsh, str| hsh[str] = str.upcase } # => {'foo' => 'FOO', 'bar' => 'BAR'}

I like the functionality but we could make this a backport of the 1.9 feature each_with_object right?

That'd involve changing the name and the order of arguments

- State changed from “new” to “committed”
(from [10fe6a6d8940300dd6698ec38e9c9573404e687d]) Add each_with_object from 1.9 for a more convenient alternative to inject.
