hello all,
i'm new to ruby and need some help on what seems like a simple issue.

How do i find out if the argument passed to a method is a string or an 
integer?

Here's what i'm trying to do:

def method_test(some_arg)
  if some_arg is string
    #callmethod A
  else
    #callmethod B
  end
end

Thanks for your help.

Parv
