This works, but I'm not sure it's what you want...

class TestClass
 def initialize(process)
  @process = process
 end

 def run()
  if @process == nil then
   puts "No process given"
  else
   @process.call("this", "that")
  end
 end
end

def testfunc(a, b)
 puts "1 -> #{a} 2 -> #{b}"
end

fred = TestClass.new(method("testfunc"))
fred.run

You may instead want to use send.
