! clj

(! f)

Takes a fn f and returns a fn that takes the same arguments as f, has the same effects, if any, and returns the opposite truth value.

φ clj

(φ f)

(φ f arg1)

(φ f arg1 arg2)

(φ f arg1 arg2 arg3)

(φ f arg1 arg2 arg3 & more)

Takes a function f and fewer than the normal arguments to f, and returns a fn that takes a variable number of additional args. When called, the returned function calls f with args + additional args.

∘ clj

(∘)

(∘ f)

(∘ f g)

(∘ f g & fs)

Takes a set of functions and returns a fn that is the composition of those fns. The returned fn takes a variable number of args, applies the rightmost of fns to the args, the next fn (right-to-left) to the result, etc.

∮ clj macro

(∮ a b)

Create a clojure.lang.MapEntry from a and b. Equivalent to a cons cell. flatland.useful.experimental.unicode contains a shortcut to this, named ·.
