And, I now realize, if someone posted what I posted and I were
responding to it, I would point out that:

   array.each {|e| puts e }

is the same as:

   puts array

Something I've described in the past as a nuby rite of passage, I
believe... :-)

I don't think I've ever seen that one.  So why is everyone so vexed
about what's going to happen with this in 1.9? :-)  (I know... it's
