Subject: Re: Inspect method

inspect is especially useful in logging/debugging.  Apparently, irb
calls inspect when outputting the value of an expression.  Check this
out:

ree-1.8.7-2011.03 :007 > a = [1,2]
 => [1, 2]
ree-1.8.7-2011.03 :008 > a.to_s
 => "12"
ree-1.8.7-2011.03 :009 > a.inspect
 => "[1, 2]"
ree-1.8.7-2011.03 :010 > h = { :fruit => 'apple', :color => 'yellow' }
 => {:fruit=>"apple", :color=>"yellow"}
ree-1.8.7-2011.03 :011 > h.to_s
 => "fruitapplecoloryellow"
ree-1.8.7-2011.03 :012 > h.inspect
 => "{:fruit=>\"apple\", :color=>\"yellow\"}"
