Use instance variables.

-------------------------------------

#!/usr/bin/ruby -w

class BlockTest
   attr_accessor :val
   attr_accessor :myblock
   def process(&block)
      self.myblock = block
   end
end


t = BlockTest.new
t.val = "Daniel"
t.process {
   "var = #{t.val}"
}

p t.myblock.call

-------------------------------------

I understand this is not a particularly pretty example, it is just meant to
show one approach.
