Subject: method_missing question

Hello,

I am using method_missing to build a structure (similar to a tree) like
this:

P.book do
  P.title
  P.price
end

class P
  def self.method_missing(method_name, *args, &block)
    #add a node with name 'method_name.to_s' to the tree etc.
  end
end

Now, the problem is I would like to write the above example like this:

book do
  title
  price
end

i.e. without the Ps.
P's sole purpose is to define method_missing - I did not want to
override Object.method_missing since I would like to release this code
to the wild and I think it could collide with my potential future user's
Object.method_missing.

I have then experimented with modules (mimicking namespace
functionality) but that still did not provide the possibility to omit
the class name. I would need something equivalent to include - you can
omit the module name if you include the module - but with classes.

I have no idea if this is possible in Ruby, but is there something like
run this code in a different context or something?

TIA,
Peter
