Perhaps you will be satisfied that the block receive values from the parent
environment. This is the normal way to solve the problem.

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

#!/usr/bin/ruby -w

class BlockTest

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


t = BlockTest.new
t.process{ |v|
   "var = #{v}"
}

v = "daniel"
p t.myblock.call(v)

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

"var = daniel"
