I believe that the canonical way of working with XML documents in Guile is through the (sxml simple) module (and others): https://www.gnu.org/software/guile/manual/html_node/SXML.html It contains xml->sxml function which allows to convert XML strings to a more familiar s-expression based format.

Re: (ice-9 nice-9) module update

Also, I've just noted that now (ice-9 nice-9) exports only 8 bindings, so there's surely a slot for defining some new ones. Perhaps it would make sense to liberate letrec or letrec-syntax, so that it would be possible to use it in a manner similar to let and letrec. However, I don't think that

Hi, it's been over a month, and I finally had an opportunity to take a closer look at your signal library (and also the video demonstration available at your blog). I have to say that I'm truly impressed with the code and grateful for it, and I find it very inspiring. However, if it comes to the
