On the behaviour of Enumerable#reduce(&.+)

Fine by me, but what is a scenario where calling reduce with a proc consuming only one arg makes sense?

For reduce, there’s obviously meaningful use case for a block that uses only the first arg. So the bottom line is, you effectively can’t use the short syntax for that. (unless we introduce a means to reference positional block arguments as suggested in RFC: `&.` within a block - #12 by vlazar)
