Okay, I've implemented it slightly different:

   require 'facet/binding'

   def args_to(types = {})
     Binding.of_caller do |binding|
       types.to_hash.each do |arg, type|
         binding[arg] = binding[arg].send("to_#{type}")
       end
     end
   end

   def test(foo, bar, baz)
     args_to :foo => :sym, :baz => :s
     return foo, bar, baz
   end

   p test("foo", "bar", 42)  #=> [:foo, "bar", "42"]
