Subject: Setting arbitrary objects

Hi.

For a kind of DSL, I need the following:

  joker.id = 'koko'
  garfield.colour = 'green'
  superman.speed = 55

I think I can solve this with OpenStruct partially.

BUT, my problem is:

Is there any way to actually make joker, garfield, superman work as is?

ALL of these are not known when I run the file! They must be created
dynamically.

I was thinking I could dynamically create methods like

def joker()
def garfield()

etc...

I can find out the name, like so:

begin
  joker.id = 'koko'
rescue NameError => error
  object_name = error.name
  method_name = ???
  exit
end


This would give me the name "joker" as result and I could dynamically
create a method called joker, which could return an OpenStruct.

BUT, how do I obtain the information that we wish to set the .id value
on that object?
