Apologies for the delays, we’re pioneering “slow dev” I guess. :-)
Haha no issue at all!

In that case, please hold on the patch. I am currently "rounding out"
the "one true Transducer API" in several other Lisps, and am close to
what I consider a representative set of the desirable primitives a
developer would want out-of-the-box. One I'm done there, I will return
to this and a few things that are currently missing.
The other Lisps have also achieved a zip-like pattern (i.e. passing
multiple collections to `transduce` at the same time, thus allowing
functions like `map` to operate on multiple inputs).
There is also the issue of SRFI-171's disambiguated `transduce-list`,
`transduce-vector`, etc., since Scheme has no `defgeneric` by default.
Guile _does_ however, so we could write a generic `transduce` in Guile's
own extensions. In general though it would be nice if SRFI-XYZ
"Transducers Redux" could depend on a standardized generics system, but
alas.
Anyway, thanks for getting back to me. I'll return to this effort in due
time.
Cheers,
Colin
