Subject: Array#to_s in Ruby 1.9 Head

Mauricio Fernandez writes in http://eigenclass.org/hiki.rb?Changes+in 
+Ruby+1.9+update+5
that Ruby 1.9 Head has changed Array#to_s to be an alias for  
Array#to_inspect.

What is the motivation for that change?
	print a
becomes
	a.each { |x| print x }

It seems like an unnecessary change that takes away a very nice  
default behavior.

I have a situation where I represent a tree of objects as nested  
arrays.  I can convert the
entire tree to a string via a pre-order traversal as:

	text = tree.to_s

I like that.
