Not sure if these are actual errors, but after scratching my head
halfway thru my scalp, I'm none the wiser.

"Because unless is the opposite of if, the else clause 
 will be executed if the condition is false."

I thought it was the opposite:
  unless false then "THEN" else "ELSE" end  #=> "THEN"

______
* s140
"The method length [...] the number of elements in an array. 
 Note that this is one less than the index of the last item:"

Isn't it the opposite?
  a = ["first", "second", "last" ]
  a.size            #=> 3
  a.index("last")   #=> 2

If these aren't errors, I hope someone can plaster the hole in my head
that is leaking. :-)

Unfortunately, I haven't gotten much farther than this yet. I'll keep my
eyes open for other compile errors in my head as I read along. (What
I've read so far is quite excellent!)

P.S.: If Sams takes forever to get up somewhere to enter errata and
such, how about a temporary spot on the Wiki pages on RubyGarden? (If
its still up that is, I can't reach it right now)
