This seems doable.

Compared to the previous approach this seems vastly more complex.  It’s
one thing to *execute* Snakemake code without running it through Python,
but quite a bit more challenging to transpile Python to Scheme.

Personally, I wouldn’t know where to start.  Do you have an idea
already?
