Hi -
For a variety of reasons I have the following situation:
---- file_a.rb --------------------------------------
class A
... magic loading goes here...
end
···
--------------------------------------------------
---- file_b.rb --------------------------------------
class B
... magic loading goes here...
end
--------------------------------------------------
---- magic_file.rb -----------------------------
... does some stuff... ----------------------------------------------
How can I include the contents of magic_file.rb into both a and b "as is". I've tried load() and it changes the scope so that magic_file.rb doesn't realize it's in A or B.
I guess I'm looking for the PHP include() equivalent.
I realize this is a weird question and I realize in most situations this is *not* the way to do it, but I don't have a choice... so please no "do it this other way" solutions 
Thanks!

class A
eval(File.read("magic_file.rb"))

I believe the following is your only choice:
eval File.read("magic_file.rb")

I realize this is against your "no other solutions" rule, but why won't
% cat magic_file.rb
module Stuff
...
end
% cat a.rb
class A
require 'magic_file'
include Stuff
end
work?

Interesting solution. What about its effectivenes? And in general,
effectivenes of require'ing something vs. eval'ing it?

Well require-ing only parses the file once. Other than that, this takes more memory (since it puts the entire file inside a string) but other than that I'm pretty sure the difference is effectively zero. The 'ideal' solution to this problem would be if load took an optional binding argument
e.g.:
class A
load("magic_file.rb", false, binding)
end

Not sure... (i'm fairly new to ruby) but I tried it and it doesn't. Here's specific details on what I'm doing (rails web services):
-philip
% cat magic_stuff.rb
module FindNewerThan
def self.included(other)
other.class_eval do
api_method :find_newer_than,
:expects => [{:created_at => :datetime}],
:returns => [[Class.const_get(self.name.to_s.gsub(/Api$/, ''))]]
end
end
end
% cat a.rb
require 'magic_stuff.rb'
class A
include FindNewerThan
end
class B
include FindNewerThan
end
etc...
