Subject: Joining an Array of Arrays

Hi,

I tried joining an Array of Arrays, and it seems the Array
is being flattened first or something.

ri Array#join tells me:
  Returns a string created by converting each element of the array to
  a string, separated by _sep_.

Its the part about each element getting converted to a string that
seems wrong:

> x = [[1, 2], [3, 4]]
> print x[0].to_s, ' ', x[1].to_s #=> "12 34"
> x.join(' ')                     #=> "1 2 3 4"

I expected join to produce "12 34"; why doesn't it?
