How about a loader that renames all global names to gensyms by default, but with the ability to preserve the ones you want?

  (load-hidden "arc.arc"
    w/infile w/outfile expander)
This basically means you have to declare every global you want to make available from the file you load. You could even specify what names to give them:

  (load-hidden "arc.arc"
    w/infile w/outfile expander.w/close)
Nested loads would be tricky though. The outer would have to hide names that are preserved by the inner, except when they are wanted of course.

Alternatively, the loader could add a prefix (the file name?) rather than rename to gensyms.
