Yes, notably all the .rb files. > The Ruby source should be there in plain text.

I hadn’t noticed, but since all the .rb source files are there, uncompressed, that means that if a reference is embedded in the source, it *will* be scanned correctly by the GC. So maybe there’s no real problem, after all. Thanks, Ludo’.
