Single array expansion is not always performed. It depends on the form of the block arguments. As you said, {|a| } doesn't expand. If {|a| } expands an array, we cannot get an element of a nested array in [ary, ary, ...].each {|a| ... }. Also, {|*a| } doesn't expand. If {|*a| } expands an array, we cannot pass block arguments as-is using {|*a| yield *a }. I wrote about this design in [ruby-dev:38795]. It is written in Japanese, though. -- Tanaka Akira
