I think I've more or less decided that I want a #reStructuredText to SXML parser in R6RS #Scheme.
I'm going to try to spend 30 minutes a day working on one, and see how I get on.
rST has been a text-based markup of choice for many years (alongside org-mode), and I was always disappointed by the ascendancy of the inferior #Markdown. It deserves an independent reimplementation.
