I just wanted to throw in that I'm in the camp of people who use begin
end when the side effect is important and braces when the return value
is important. This conveys  more meaning on a causual glance. I.e.

print "100!"
puts (1..100).inject(1) { | r, i  | 
  r*i 
}

(1..100).inject(1) do | r, i | 
  puts "#{i}! = #{r = r*i}" 
end
