Subject: iteration the ruby way

Hi,

I have a question about The Ruby Way.  Pickaxe gives the following
example for using iterators in Ruby:

a = [ "a", "b", "c" ]
a.each {|x| print x, " -- " }

This outputs:

a -- b -- c --

But what if I want to print "a -- b -- c"?  What's the proper Ruby way
of doing that?  Is there some way of detecting the last element?  I
mean, obviously I can do it with a for/while loop or something...

Thanks,
Navin.
