Lars, how about the performance of the set operations (difference,
union, subset/superset, intersection)? Were you planning to do those in
C as well? They'll benefit from a fast range-memq but they would still
do a lot of ELisp work.
Can ranges be an opaque type (with rangep, make-range, etc.) so the
implementation is irrelevant to the user? That seems the best
compromise between performance and maintainability. As long as you can
read and print ranges in a consistent format, that is.
Depending on the expected size and performance, the internals can
convert between bool-vectors, binary trees, inversion lists, plain
lists, whatever.
Ted
