It does not seem to handle OP's problem though, which are locals or am I wrong?
My idea would be to use Smalltalk constants, does anybody save Rick
know what that is? ;)
But of course constants are not enough so I will define setters too :)

But I am not sure if that works <blush> let me see:
Yup seems to work

file: test1.rb
a="sourced a"
b="sourced b"

file: main.rb
a = "Main a"
eval File.open("test1.rb"){|f| f.read } << %{
  local_variables.each do |lvar|
     this = class << self; self end
     this.send :define_method, lvar do eval lvar end
     this.send :define_method, lvar + "=" do |new_val|  lvar = new_val end
  end
}
p [:now_a, a]
p [:now_b, b]
b = "changed"
p [:changed_b, b]

----------------------------------------------------------------
Now it depends very much on the use case if you can live with this.
Any pitfalls I have overseen?
