def try(*args, &block)


delegate the `try` call to the underlying vlaue fixnum.
If we respond to the first argument, `__send__` the args. Otherwise,
the underlying fixnum doesn't respond to all methods (e.g. name or value).
Re-implement `try` in order to fix the problem where 
def try(*args, &block)
  case
  when args.empty? && block_given?
    yield self
  when respond_to?(args.first)
    __send__(*args, &block)
  else
    @value.try(*args, &block)
  end
end
