Use of "next" in Ruby 1.9?

C

Charles Turner

Hi all-

Fiddling around with external iterators in Ruby 1.9,
and had a question. Given the following method definition:

def twice
if block_given?
yield 1
yield 2
else
self.to_enum:)twice)
end
end

Why does:

iter = twice
puts iter.next

display output, but:

iter = twice
iter.next {|x| puts x }

doesn't?

Best, Charles Turner
