bindclj
(bind f [val err])Call f on val if err is nil, otherwise return [nil err] See https://adambard.com/blog/acceptable-error-handling-in-clojure/.

deep-merge-withclj
(deep-merge-with f & maps)Like merge-with, but merges maps recursively, applying the given fn only when there's a non-map at a particular level. (deep-merge-with + {:a {:b {:c 1 :d {:x 1 :y 2}} :e 3} :f 4} {:a {:b {:c 2 :d {:z 9} :z 3} :e 100}}) -> {:a {:b {:z 3, :c 3, :d {:z 9, :x 1, :y 2}}, :e 103}, :f 4} Taken from https://clojuredocs.org/clojure.core/merge-with.

just-thenclj
(just-then maybe just-fn)(just-then [val error] just-fn nothing-fn)Given a maybe ([just nothing]) and a just function that returns a value given
the just as input, return that value, or a nothing ([nil error]) if
error is truthy.
Given a maybe (`[just nothing]`) and a just function that returns a value given the `just` as input, return that value, or a nothing (`[nil error]`) if `error` is truthy.
just-then-escclj
(just-then-esc maybe)(just-then-esc maybe just-fn)(just-then-esc [val error] just-fn nothing-fn)maybe-reducerclj
(maybe-reducer f)Takes a reducing function and returns one that short-circuits on an accumulator argument that is a Nothing 2-vec, i.e., a vector with a non-nil second item.

maybes->maybeclj
(maybes->maybe maybes)Convert a sequence of maybe Xs (2-vecs) to a single maybe sequence of Xs.
