But the method name is short and expressive.  I like that. :-)

Hm, from `eachn' I'd expect:

  a.eachn(2) do |x, y|
    ...
  end

  a.eachn(3) do |x, y, z|
    ..
  end


I'd rewrite `b = a.eachn(2)' in:

  b = a.collectn(2) {|a, b| [a, b]}


For which an optional blockless form would make sense:

  b = a.collectn(2)
