def initialize
  @params={}
end

def param
  @params
end

my_object.param["tag"]="new value"

If you need some sort of validation, you can have param return some other 
class that defines [] and []= and does the necessary validation, and you 
can even set up an easy method for defining the param attribute to do all 
of that if need be.
