fun with bindings

binding.rb

def with_binding(b)
  vars = eval('local_variables', b)

  vars.each do |v|
    eval("#{v} = #{eval(v.to_s, b)}")
  end

  yield
end

a = 5

with_binding(binding()) do
  puts a
end

Problem? :^)

Because it's the morning, I forgot that the block would already capture the binding...

def whatevs
  yield
end

a = 5

whatevs do
  puts a
end
