call clj

(call obj)

(call obj f)

(call obj f v1)

(call obj f v1 v2)

(call obj f v1 v2 v3)

(call obj f v1 v2 v3 v4)

(call obj f v1 v2 v3 v4 & vs)

like invoke but reverses the function and first argument

(call 2) => 2

(call 2 + 1 2 3) => 8

invoke clj

(invoke f)

(invoke f v1)

(invoke f v1 v2)

(invoke f v1 v2 v3)

(invoke f v1 v2 v3 v4)

(invoke f v1 v2 v3 v4 & vs)

Executes (f v1 ... vn) if f is not nil

(invoke nil 1 2 3) => nil

(invoke + 1 2 3) => 6

message clj

(message obj kw)

(message obj kw v1)

(message obj kw v1 v2)

(message obj kw v1 v2 v3)

(message obj kw v1 v2 v3 v4)

(message obj kw v1 v2 v3 v4 & vs)

Message dispatch for object orientated type calling convention.

(def obj {:a 10 :b 20 :get-sum (fn [this] (+ (:b this) (:a this)))})

(message obj :get-sum) => 30

op clj

(op f & args)

loose version of apply. Will adjust the arguments to put into a function

(op + 1 2 3 4 5 6) => 21

(op (fn [x] x) 1 2 3) => 1

(op (fn [_ y] y) 1 2 3) => 2

(op (fn [_] nil)) => (throws Exception)
