Hi,

What is the best practice in Ruby regarding creating methods?  Is it to
create a named set of parameters to pass (specific method signature) OR
should I be passing a hash which may be more readable/future proof?  For
example:

Option 1 - Named
   -  def this_method (time, search_string, something_else)
   -  a = this_method (11, "asdf", "asdf asdfa")

Option 2 - Hash
   - def this_method (params)
   - a = this_method (:time => 11, :search_string => "asdf", :something_else
=> "asdf asdfa")


Option 2 seems to be more readable and flexible from what I can see.  Is
this the recommended Ruby best practice for implementing Ruby methods that
have more than a couple of parameters which have to be passed?

Regards
Greg
