This proposal is subsumed under the first phase of Error Handling

Goals:

Approach:

Stacktrace handling can be divided into three parts: collecting and parsing the exception data, filtering/transforming that data as appropriate for Clojure, and then rendering that data according to some design.

To facilitate steps 2 and 3 for Clojure itself and also for other library developers, we propose to first parse exceptions into Clojure data structures and to provide this data as input to the filtering/transforming and rendering phases.

The data-based approach is used by clj-stacktrace.

clj-stactrace, clojure.repl, and clojure.stacktrace all have different takes on the formatting aspect of stacktrace presentation.
