I thought your module/library was impressive.  My little macro (as it
now turns out, defective in hygiene, although it has served me well for
some time) was something I use frequently because I like the pipeline
idiom.  It inserts to the right only, because that is what I am used
to: it sort-of imitates the reverse application of a partially applied
curried function.  I think your module is based on clojure macros,
about which I know little.
