Ok, I started a guix lint on 0.14.0.1183-1b321.

Will attach log here asap.

I agree that some heuristics to figure out the file-name from (svn-reference-url ref) would be nice.

It's not that important that the store filenames are meaningful to humans, it's just nice-to-have.  So I'd say heuristic it and be done with it.

On second thought, maybe even default file-name to the Guix package name (if possible at this point in Guix).  The hash value will make it unique regardless (for example if there are multiple svn-download blocks in the same package)
