compare-chainclj/smacro
(compare-chain)(compare-chain x)(compare-chain x & next)This is a convenience macro for writing comparators with complex precedence rules.
Continues comparing down the chain until a comparison returns not equal (a value other than 0 or nil). Otherwise, the two values are considered equal and 0 is returned.

parse-natural-numberclj/s
(parse-natural-number s & {:keys [throw-exceptions] :as opts})Parses a string to a natural number. Returns nil if not given
valid input, unless :throws-exception is set. This function also
automatically promotes to BigInt if needed.

re-linkedclj/s≠
(re-linked re s & {:keys [throw-exceptions] :as opts})Returns a collection of successive matches of pattern in string,
but allowing no gaps between the matches. In other words, the
end index of the first match must be equal to the start index
of the second match, and so on until there are no more matches left.
