Thanks Doug! git fsck appears to do exactly what I wanted. All praise
to Torvalds and Git.
Abram's particular problem, I believe, was in copying multidimensional
arrays. He ended up writing his own function to copy his Tron game
This seems to be a known "hole" in the Common Lisp spec.. e.g. a
library called cl-utilities provides a function called COPY-ARRAY:
The library bills itself as "things that everybody writes since
they're not part of the official standard".
