# Ruby edge cases

# lambdas can no longer be used with instance_eval in Ruby 1.9.2
l = lambda { puts "hello world"! }
Object.instance_eval(&l) #=> invalid argument. This is due to the fact instance_eval now yields a value (the receiver) in 1.9

# module double inclusion
# module appear multiple times in inheritance chain
# behaviour of constants in class_eval
# Proc.new can create a proc from an implicit block
