Hi,

Is it possible to get 2 elements at once ?

[1,2,3,4].each {|a,b| puts a;puts b;puts ‘x’}

produces

1,

nil

x

2

nil

x

3

nil

x

4

nil

x

I’d like to get

1

2

x

3

harp:~ > cat a.rb

require ‘enumerator’

puts

%w( a b c d e ).each_cons(2){|x,y| p [x,y]}

puts

%w( a b c d e ).each_slice(2){|x,y| p [x,y]}

harp:~ > ruby a.rb

[“a”, “b”]

[“b”, “c”]

[“c”, “d”]

[“d”, “e”]

[“a”, “b”]

[“c”, “d”]
