Subject: Scope of block

Hello i have a question about scopes of block
I want to define a block at one time.
But when it get's called it should have the scope (vars ed )
of the calling environement

Example :
------------------------------

class BlockTest

  attr_accessor :myblock

  def process(&block)
    self.myblock = block
  end
end


t = BlockTest.new
t.process {

  "var = #{out_of_scope_var}"
  }

out_of_scope_var = "daniel"
p t.myblock.call

Results in :

blocktest.rb:15: undefined local variable or method `out_of_scope_var'
for main:Object (NameError)     from blocktest.rb:19

How can i call the proc so that the out_of_scope_var is known :

result would be :

so i would get :

daniel-wijnands-powerbook58-2:~/jim/vendor/plugins/widget_grid/lib
danielwijnands$ ruby blocktest.rb 
"var = daniel"
