Pascal's WITH in ruby

Pascals_WITH.rb

# for a long time I wondered why Ruby didn't have Pascal's "WITH"
# construct. It's completely trivial to implent though...

def with object, &block
  object.instance_eval(&block)
end

# now instead of needing to name your object all the time:

object = Object.new
object.foo
object.bazbar

#  you can instead just do

with object do
  foo
  bazbar
end

# oh the simple wonders of metaprogramming :-o :-)))
