Given that: a) fns can have names for debugging purposes, and b) data
structures can have metadata, wouldn't it be a good idea to let let auto
attach (where possible) the names of the bindings to their corresponding
values?
For example, the improved let I'm thinking of would translate this input:
(ns my.namespace)
(defn do-it
(let [foo (fn [] (throw (Exception.)))
bar {:hello (/ 0 0)}]))
to:
(ns my.namespace)
(defn do-it
(let [foo (fn foo [] (throw (Exception.)))
bar ^{:origin :my.namespace/do-it$let$bar} {:hello (/ 0 0)}]))
This could be used to increase the precision of the stack traces, or in
IDEs/editors for locating the exact source of an exception.
Do you see such a mechanism being incorporated to clojure.core/let - should
I open a ticket?
