That's short in two respects: performance, and non-retention of formatting and
comments. We could store source refs in:
- a hash table weakly keyed on the code object
- some back corner of byte-code objects
- OClosures
We have a similar problem with regexps, which are only retained and edited in
the traditional syntax.
We are veering off-topic. Sorry about that.

Is compatibility a serious concern given that buffer-match-p is new in 29?
