Applied, thanks!

As a rule of thumb, only write ‘use-modules’ at the top level.  Use
#:modules here.

I left it here because it doesn’t matter all that much, and because we
could/should probably remove ‘guile2.0-irregex’ anyway.

I would avoid using regexps for such things: it’s heavyweight, hard to
read, and error-prone.  Looks like you could do away with just
‘basename’ and the likes, no?

Thanks,
