Delegation Benchmarks
View benchmark.rb
#
# A benchmark testing the performance of three methods of delegation:
#
# - Manually defining delegation methods
# - Metaprogramming using __send__
# - Metaprogramming without using __send__
#
# Note that the manual way of doing it is much faster if the arity of the
# target method is known. However, this benchmark is only meant to test
# the issue of __send__, and so we define the delegation methods with
