Okay, I can get that stack trace, but there's no line for clojure.core/ divide in your trace. How would I know which function threw the exception? "eval" isn't very useful. Ideally I'd like a line number, too.
If I have a function, (defn process [sequence] (map some-function sequence)) And it gets called by another function, (defn higher-up [sequence] (concat (list 1 2 3 4 5) (process sequence))) And that gets called by (higher-up 12) ;; note: 12 is not a seq Then the stack trace for "don't know how to create ISeq from 12" doesn't mention anything about 'higher-up or 'process at all. It's lazy-seq evals and fn invokes. The error occurs in a closure that was created inside these functions being evaluated to print a lazy seq, but most of the work done by programs occurs in contexts like that. If the closure can't have a context and line numbers attached, is it just impossible to have meaningful debugging and stack traces?
