assoc* clj/s macro

(assoc* m k expr & kvs)

Returns persistent map with delayed evaluations of the expr under the key k. Accepts multiple key/expr pairs. Does not delay evaluation of simple forms like constants and empty sequences.

convert-map clj/s

(convert-map m)

Converts any map to zizz map to allow access delayed values added explicitly.

delay* clj/s macro

(delay* & body)

Returns customized delay for the body to be used as zizz-map values when the map is constructed manually.

init clj/s macro

(init m)

Returns persistent map with every not simple value expression wrapped with delayed evaluation.

For example in

(def my-map (init {:a (doto :x println)}))

the expression (doto :x println) will be evaluated only when value for :a requested, i.e. in (get my-map :a).

The value expression is considered simple if it is not non-empty sequence. So in following case evaluation will not be delayed and initialization will be faster:

(def my-map (init {:a 1}))

merge* clj/s

(merge* m1 m2)

Given two maps with possibly delayed values returns merged persistent map.

update* clj/s

(update* m k f)

(update* m k f x)

(update* m k f x y)

(update* m k f x y z)

(update* m k f x y z & more)

Same as clojure.core/update but with delayed application of the function f.
