Subject: Processing code file inline

I need to have a script load a file and execute that file as if it was
code inline to the script. The file being loaded is not a class, not a
module. It is code that has been dynamically written by another process.

Example:

# file to load
index_33dob.store("NatVir20000515".to_sym, 67)
index_33dob.store("MicSwa19920210".to_sym, 85)
index_33dob.store("AshSmi19950827".to_sym, 19)
index_33dob.store("IvaCov20021108".to_sym, 45)
index_33dob.store("CatOrt19950128".to_sym, 83)

# contrived script to load the file and process it
timer_start = Time.new
index_33dob = {}
include "33dob_entries.rb"  # <<--- WHAT DO HERE ?
timer_stop = Time.new
puts "#{timer_stop - timer_start}"
p index_33dob


In other languages I have used, the command include would be used to
integrate the 33dob_entries.rb file as inline code, but neither Ruby's
include nor require can be used to do this AFAICT.

How would I do this with Ruby ?

(I am writing some data structures to disk as code instead of using
Marshal because it is actually much much faster than reconstituing the
data via Marshal, and that re-loading performance is critical to the
app).

thx
