fmtstrclj/s
(fmtstr format-in & args)Provides a marginally more convenient form of clojure.pprint/cl-format by
not requiring a writer to be specified when a formatted string is all that
is needed.

non-nil!clj/s
(non-nil! x)(non-nil! x message)Asserts (using assert) that x is not nil and returns it if it is not.
Asserts (using `assert`) that `x` is not nil and returns it if it is not.
single!clj/s
(single! coll)(single! coll msg)(single! coll empty-msg many-msg)Asserts (using assert) that coll contains only a single element; does
not realise lazy sequences.
The multi-arity versions of the functions allow additional context to be
added to the assertion message; in the arity 2 case msg is appended to
the default assertion msg, while in the arity 3 case empty-msg and
many-msg replace the default assertion message for collections with
<1 and >1 elements respectively.

The multi-arity versions of the functions allow additional context to be added to the assertion message; in the arity 2 case `msg` is appended to the default assertion msg, while in the arity 3 case `empty-msg` and `many-msg` *replace* the default assertion message for collections with <1 and >1 elements respectively.
