So the most used functions on Clojure map and filter have been modified to return transducers (composable algorithmic transformations), if not called with a collection. That means:
(map inc) returns a transducer and so does (filter odd?)
The advantage: the functions can be composed into a single f...

A vignette is a long-form guide to your package. Function
documentation is great if you know the name of the function you need,
but it’s useless otherwise. A vignette is like a book chapter or an
