The following is an explanation of Ruby blocks and yield by another Bloc mentor (Adam Louis) who was trying to explain it to one of his students.
On my very first day programming, if someone asked me for "the sum of the numbers from 1 to 10", I'd have written:
puts 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10
Easy enough.
